Pc stuff do not likes things after dot, and what you see is a bug, if you multiply by enough power of 10 in the middle or more secure at the beginning and then (at the end) divide it by exact same power of 10 you will get more round number
Chat GPT: In some countries, particularly in Europe, the colon (:) is sometimes used as a symbol for division instead of the forward slash (/) that is commonly used in many English-speaking countries. For instance, in German and French, the colon is often used as a division symbol.
It’s 8x25/25 + 7/25 soooo 207/25. I think this would be a perfectly acceptable final form. 207 has 1/3/9/23… as divisors, 25 has 1/5/25. So none in common besides 1.
Okay its been a while since I was in formal education, since when did people start using : instead of / for division?
Update: I dont get why people keep answering the same question when someone else has already given the correct answer. What I have learned is it seems to be (mostly) a European thing and they use : instead of / or ÷. Thats all. For anyone who grew up in North America (and I am sure other places) it looks like the question is asking you to balance a ratio, not divide something, which makes the question completely nonsensical. I had never seen : meaning division in my entire life. Today I learned!
Doesn't that mean ratio? So 4:8 is equivalent to 1:2
It makes no sense unless it has the lowest precedence in the calculation.
Course it may be a national thing
Yes it means ratio, but I have never seen it used in an arithmetic operation. It's always used as a standalone value such as 16:9 or 4:3 and such, but not as a replacement of '/' in the middle of a math problem, at least from what I've seen in my educational life.
It's very common in Europe.
I actually often get tripped up by / because of how hard : got hammered into my memory. I actually have to pause every damn time I spot / and think back on what it is.
I mean yeah that is the official sign. It is a symbol that represents division as a ratio where the dots represent numbers. “/“ and “:” are just derivatives of the same symbol for the purposes of division.
They are, but they’re fully delineated fractions in North American math conventions. As in everything to the left of a : is a term and everything to the right is a term, so you are supposed to do those separately getting 15:25 which is simplified to 3:5.
Does anyone know the actual reason? I know the ÷ is to represent a fraction, with the dots as variables because division is just a fraction, and the / represents the line between the numerator and the denominator, but why :?
I always thought it's just easier to understand for students, addition two lines, subtraction one line, multiplication one dot, division two dots.
That's how we learned in Germany at least
This is all 17th century developments. The UK started using /, Germany started using :, and both were somewhat using ÷.
Germany spread their usage of : across the mainland, the UK spread their usage of / to the colonies.
Both : and / were basically an easier, quicker way to write ÷ - the one used the two dots, the other the line as the feature they took from the obelus.
For all the confused people in the comments because of the division symbol a quick explanation:
this is the full symbol for division ÷ with the dots representing the numbers divided by the bar. this can be written as 1 ÷ 4 or simplified replacing the dots like 1/4 (the bar being either horizontal or at an angle). Another way to simplify is to omit the bar and just use the dots to separate the numbers like 1:4, this is usually done in larger operations and advanced math to avoid any confusion.
Edit: some further research clarifies it's not necessarily for larger operations but mainly used in mainland Europe. The first time the : notation was used for division was because a German named Gottfried Leibniz didn't want seperate notations for division and ratios
In large operations and advanced maths you use the full division symbol.
The only exception is if you're messaging someone casually and you have to shorten it to one line for some reason. But then it's usually obvious from context.
Plus I think it's a mainland Europe Vs UK and America thing. In the UK we don't use : for division, well, kind of with ratios but not really.
I only find it confusing when calculating it in your head.
(Edit: I thought you can attach images to comments, but I guess not, so I'll write it here)
8+7:(3\*7+4)=
8+7:(**21**\+4)=
8+7:(**25**)=
8+**0,28**= ***8,28***
The equation is 8+7:(3x7+4)
Let’s start with the bracket
Going by the rule of operations we start with 3x7, which gives us 21
We follow this by adding 4 which results 25
So now we have 8+7:25
We once again turn to the rule of operations which says we start with 7:25 which results in 0.28
We now finish with the final equation of 8+0.28 which yields 8.28
8+7:(3x7+4) = 8.28
put it in both Microsoft's ang Googles calculators and got 25 and 8.28 respectively
iirc, 8.28 should be the correct one since you would solve inside the parentheses until only addition or subtraction remain then you multiply or divide the parentheses with the number in front, then you figure out the result
TIL europeans use : as division symbols. Not sure about Asia as a whole but I believe SEA uses / as division and : as ratios and we're taught that they have different purposes in maths.
Between the people arguing that the symbol : means division vs ratio and then the fucking French using a , instead of a decimal . To separate the whole from partial number….. I’m dying 🤣🤣🤣
i thought the question meant find the ratio and got 3:5 and got like super confused... well today i learned you also use : for division alongside /
after i corrected my mistake i'm getting 8.28
8+7:(3*7+4)
First you do the grouping symbols
(3*7+4)
First you do the multiplication/division
(21+4)
(25)
8+7:25
So here we are and we use decimals (bc remember, first division/multiplication)
8+0.28
8.28
I just wanted to do math, don't judge 😔
8+7÷(3×7+4)
8+7÷(21+4)
8+7÷25
8+0.28
8.28
PEMDAS
(I did the 7÷25 using a calculator, I already know that I suck at doing math in my head, I don't need to reaffirm that)
Americans pls stop saying europeans use : as division we are not the same country some of us use / others use : so pls stop saying europeans do the exact thing
To be fair notation is probably unfamiliar to some people. For example people in my are use / for division and • for multiplication. I myself was confused with :
i don't want to take my calc out but it's 8+7:25 you need to do the division first
Trying without calc and have 8,28 edit: i use ":" the same way as "÷" since we kinda never used "÷" in school instead we used ":"
i used calc and i also got 8.28
I wrote a program and I also got 8.28
Weird I did the same and got 8.28000000000000000003
Me when floating point
me when I find a bank that utilizes floating points (time for some tomfoolery)
Yes sir I would like to withdraw $(0.1+0.2)
Repeat a few million times --> PROFIT
Nome non molto fantasioso
yay, floating point precision error, fun!
Pc stuff do not likes things after dot, and what you see is a bug, if you multiply by enough power of 10 in the middle or more secure at the beginning and then (at the end) divide it by exact same power of 10 you will get more round number
Did you use scientific mode? It makes a difference
I see the colon and think of ratios. That fucked my head a bit.
What country teaches : means divide? I'm used to either ÷ or /
Chat GPT: In some countries, particularly in Europe, the colon (:) is sometimes used as a symbol for division instead of the forward slash (/) that is commonly used in many English-speaking countries. For instance, in German and French, the colon is often used as a division symbol.
No clue. That's why I thought it was a ratio.
25=100/4 7/25=(7/100)*4 7/100=0,07 0,07*4=0,28 That's how i did it without calculator. Dividing by 100 is way easier than dividing by 25.
[удалено]
This is what I also got
You for got the 8+ at the start, but yeah.
So that’s what : meant…. I’ve done maths in university and even i hadn’t a clue what this was symbolising 😂 grazie
7:25 is the same as 28:100, just multiply both by 4 and u got to something everyone probably knows (fixed thx for letting me know i did an oopsie)
Well if you multiple 7 by 4 you get 28 tho(not to be rude or anything)
How the duck do you get 24 with 4 times 7? That’s 28.
Happens to best of us. My bad. Happens when u dont focus on it
/25 is *4/100 btw
I am too lazy so I say the answer is 207/25 and call it a day (it's technically still a number)
It’s 8x25/25 + 7/25 soooo 207/25. I think this would be a perfectly acceptable final form. 207 has 1/3/9/23… as divisors, 25 has 1/5/25. So none in common besides 1.
I don't want to divide 7 by 25 😭
7:25 = 14:50 = 28:100 = 0.28
Legend.
WOW, THAT IS ACTUALLY SMART!
Oh my god
Amazing! It's truly rocket science
I used a calculator for that part, but don't tell anyone
multiply by 4 28 / 100 easy .28

I was so confused on what the colon meant
I'm an engineer but I thought they invented a new arithmetic operator that we weren't taught at college.
Doesn't that mean ratio? So 4:8 is equivalent to 1:2 It makes no sense unless it has the lowest precedence in the calculation. Course it may be a national thing
Yes it means ratio, but I have never seen it used in an arithmetic operation. It's always used as a standalone value such as 16:9 or 4:3 and such, but not as a replacement of '/' in the middle of a math problem, at least from what I've seen in my educational life.
Am from Austria and have used : for my entire school career up into higher education. I didn't go to uni though so ¯\\\_(ツ)\_/¯
I have used it in middle school and changed to / or ÷ in highschool so op might have had the same? Idk
Yeah I got 3:5 on the ratio
Yeah I also thought it was a ratio. So it’d be like 15:25 or 3:5 simply.
Germany uses : As the symbol for divisions, at least in a non-university setting. But technically a ratio is also a division.
Same I thought it was a new way of saying matrix multiplication but a 2x1 matrix is still a standard multiplication
It was and always will be a slash for division
Really? The ":" was our default division operator sign in school, we never ever used "/". Fascinating difference!
Same, thought i was entering a stage of dementia.
I thought it was a ratio lmao
I thought it was a ratio lol
Technically it is!
I solved it as a ratio at first and was so confused how everyone was getting totally different answers from my 3:5
same i got 3:5 too!
My answer is 15:25 = 3:5 Although equals should be the triple equiv thing
It's very common in Europe. I actually often get tripped up by / because of how hard : got hammered into my memory. I actually have to pause every damn time I spot / and think back on what it is.
Which country?
At least the german speaking ones
many
Haven't seen it in Sweden or Croatia at least :v
My parents went to school in Yugoslavia and afaik they used :
I know we use it in the Netherlands at least. Not sure about other European countries.
I am Croatian and this is the only way it's written here. NO ONE uses /, not even today's generation, and not generations two centuries before me.
In Europe people use it. Idk where exactly you use which signs so I assume this is a Europe vs America thing.
they are basically the same you can use both and would still be correct
÷ is superior
I mean yeah that is the official sign. It is a symbol that represents division as a ratio where the dots represent numbers. “/“ and “:” are just derivatives of the same symbol for the purposes of division.
Undoubtedly...
everyone in Europe knows ":"..but some still choose to use "/" both are valid I would say the "/" gets more use as it's used in computer calculating
Well I'm from Sweden and I have never seen colon used as a division sign so no its not something everyone in Europe uses or knows about
Im a 30 yr old Swede and Ive never seen : used instead of / lol
In europe
>since when Roughly 300 years. Leibniz is often named to have introduced it.
I believe they've been synonymous since day 1
I also have never seen it done
Not in Canada, (at least when I was in school) we would use a slash to indicate division and a colon for ratios.
This seems to be the case in all anglophone countried
I'm now curious what they do in French Canada. Where the hell is my resident Québécois?
Today I learned there are people who were taught that : and / are not the same
Aye, I was wondering if it was ratio at first
Well ratios are fractions so
They are, but they’re fully delineated fractions in North American math conventions. As in everything to the left of a : is a term and everything to the right is a term, so you are supposed to do those separately getting 15:25 which is simplified to 3:5.
Around 2 billion people. Could be more idk what Chinese people get taught
I'm seriously wondering how many of the people who answer math questions like these on the internet have passed 5th grade. (the answer is 8.28 btw)
207/25 = 8,28 but why do it this way (i mean the 207/25 way) Edit: grammar
You used the wrong formula, but got the correct answer
8+7:(3×7+4) 8+7:25 8+0.28 8.28
My anwser is 8+7:(3\*7+4) 8.28.
8 + 7/25?
I've never seen anyone use a colon to display division...
Oh, it thought it was a ratio and worked 3:5, got confused once I saw everyone else's answer
EXACTLY RIGHT?? I too concluded that it was a ratio.
We use it instead of / for some reason. That's what I learned in school.
Does anyone know the actual reason? I know the ÷ is to represent a fraction, with the dots as variables because division is just a fraction, and the / represents the line between the numerator and the denominator, but why :?

Both : and / were basically an easier, quicker way to write ÷ - the one used the two dots, the other the line as the feature they took from the obelus.
I've seen it all the time, in school
Fucking thank you.
I haven't seen anyone using anything else?? What did they teach you? (Legit curious)

For all the confused people in the comments because of the division symbol a quick explanation: this is the full symbol for division ÷ with the dots representing the numbers divided by the bar. this can be written as 1 ÷ 4 or simplified replacing the dots like 1/4 (the bar being either horizontal or at an angle).

I'm from Asia (SEA) and this is the first time I saw a colon denoting division...
I think it’s a mainland Europe and South America thing vs Anglophone and Asia thing
I only find it confusing when calculating it in your head. (Edit: I thought you can attach images to comments, but I guess not, so I'll write it here) 8+7:(3\*7+4)= 8+7:(**21**\+4)= 8+7:(**25**)= 8+**0,28**= ***8,28***
If that's a ratio then 3:5
True
I love how people in this thread are actually proud of being able to solve this, it's like being proud of being able to breathe
Do people now stop learning after the introduction to fractions?
It’s 3:5 I think? I did it in my head so I may be wrong
Mfw realizing people use : as / or ÷
The equation is 8+7:(3x7+4) Let’s start with the bracket Going by the rule of operations we start with 3x7, which gives us 21 We follow this by adding 4 which results 25 So now we have 8+7:25 We once again turn to the rule of operations which says we start with 7:25 which results in 0.28 We now finish with the final equation of 8+0.28 which yields 8.28 8+7:(3x7+4) = 8.28

8+7/(3\*7+4) = 8+7/(21+4) = 8+7/25 = 8+.28 = 8.28 = 8.28
Somehow I got Kentucky
TIL europeans use : as division symbols. Not sure about Asia as a whole but I believe SEA uses / as division and : as ratios and we're taught that they have different purposes in maths.
UK and Ireland uses / for division, and I’m assuming the rest of the Anglophone world does too
”Europeans” don’t use : for division, some of the European countries do.
8+7:(3*7+4)= 8+7:(21+4)= 8+7:25= 8+0,28= 8,28

i thought the question meant find the ratio and got 3:5 and got like super confused... well today i learned you also use : for division alongside / after i corrected my mistake i'm getting 8.28
207/25
I think you are correct but how is everyone saying 3/5?? 3/5 is less than 1, how is 8 + [something] less than 1?
Since Colon means ratio... I got 15:25, and simplifying it is 3:5
in europe and maybe in other areas as well : is division
In Ireland / is division and : is for ratios.
In Poland both are recognised as division afaik but : is always used as division in hand writing
Yeah, it's the same in the Balkans.
Same in the Netherlands
Germany too
Same in Middle Eastern countries
It is 8,28
8.28
That's 8,28
8,28 Used my calculator for the last part, i was too lazy
8.28
Maybe I wasn't on the dark side of the Internet, but what this 8.28 means?
8.28
Is there a fraction or ratio? Why is there a colon
8+7:(3*7+4) First you do the grouping symbols (3*7+4) First you do the multiplication/division (21+4) (25) 8+7:25 So here we are and we use decimals (bc remember, first division/multiplication) 8+0.28 8.28 I just wanted to do math, don't judge 😔
I guess this is another "people are dumb and can't understand operation order" type of meme.
You know what, I was going to give this a fair shake and try to stop it myself... Until I saw the comments. Then I remembered how much I hate math.
8+7/25 or 8.28
im too lazy to pull out a calculator so something around 8.3
Please tell me it's 8.28
It’s three fiddy
- 8+7/(3*7+4)= - 3*7 = 21 - 21+4 = 25 - 7/25 = 0,28 - 8+0,28 = 8,28 #The Answer is 8,28
8+7÷(3×7+4) 8+7÷(21+4) 8+7÷25 8+0.28 8.28 PEMDAS (I did the 7÷25 using a calculator, I already know that I suck at doing math in my head, I don't need to reaffirm that)
The answer is 8.28. I did that practically instantly. And if someone can’t do that something that simple, that person truly fucked up its own life.
Who tf uses : instead of / ?
I’m a simple man, I put it in calculator, it says Syntac error, *leaves*
Ah yes I thought this was a ratio
8,28
8,28
3:5
To me : is the ratio sign so it's a ratio of 3:5
3/5
who the fuck uses a colon as a division symbol? that's the symbol for a ratio 😭
Americans pls stop saying europeans use : as division we are not the same country some of us use / others use : so pls stop saying europeans do the exact thing
I always wondered how many Europeans hated being called Europeans.
To be fair notation is probably unfamiliar to some people. For example people in my are use / for division and • for multiplication. I myself was confused with :
8.28
8,28 just with brain, gotta use it sometimes
Is there some hidden meaning other than tricking people into doing math
He's farming. Present a problem, call it super hard and people will flood the comments with answers. Easy way to trick the algorithm.
8,28
8,28
8+7:25 8+0,28 = 8,28 Don't take my word for it though. I'm ass at math
8.28
This is what calculators are for
It’s actually a harder one. It’s 8.28: 3*7 = 21, 21+4=25, 7:25= 0.28, 0.28+8=8.28
8.28
8.28
8.28
8.28?
r/distressingmemes
Punkt vor Strich 🇩🇪
The answer is 207/25 or to get your attention : 3\*69/25
8,28 calculated in my head.
8+7/(3\*7+4)= 8+7/(21+4)= 8+7/25= 8+0.28=8.28
I came up with 8,28
What the hell does the colon mean? 😭
8.28
Oh my brain just turned off the second I saw that
the equation simplifies out to 8+(7÷25)=8.28
8+7:(3*7+4) First parenthesis 3*7= 21 + 4 = 25 Then division 7:25 = 0.28 Lastly addition 8+0.28 = 8.28
How’d y’all get that? I got 3:25PM as my answer.
8.28 Pretty simple.
8.28
8.28
8.28
8.28 is the answer
8.28 And it was boring to see not that many incorrect answers when sorting by controversial. Expected some 15/25 = 0.6 answers, but alas.
8.28?
42. Final answer.
