how is 2*(3/5) = 13/5?

>>16178541
What? Do you not realize that 1.5 is the same as 1 and 1/2??
>>16178543
5 is the divisor of the fraction, if you divide 1 into 10 parts you can express it as 10/10, so 15/10 would be 1 and 5/10, you're just using fractions instead of decimals

5/5 + 5/5 + 3/5 = 13/5

but that's 2+(3/5), not 2*(3/5) = 1.2, is it supposed to be a sum?

It's neither, do you see any parentheses nigga?? It's two and three fifths

it should be like 5½, like in screw sizes and things like that

>>16178564
should i read this as 3+(1/8) too because it doesn't have parenthesis?

Probably, yes, unless your fraction is visibly separated from the integer with some operation, if that's not what was meant then it is an error by the person who came up with it

When was that, 600 B.C.?

Unless you went to school in some parallel universe that mixed with this one Berenstain-style, then you should have seen that notation in school. The most probable explanation is that you just forgot it.

>>16178558
Yes, it's a sum, but we usually think of it as just another format for writing a number.

>>16178573
Yes.

I have used this since forever since thats how imperial units in mechanical items are written. I didnt know that had a name, i thought it was just a custom

I had to explain to a student today why you can't do this:
[math]\frac{1}{3}196\pi h = 849\frac{1}{3}\pi[/math]
[math]196h = 849[/math]

why not? is that supposed to be 1/3 + 193?

No one uses this notation outside of elementary school since it is quite confusing
At least, I haven't seen it in years (as a mathematician)

well, I learned mixed fractions in the 80s, so I think you're wrong.

The [math]\frac{1}{3}196[/math] means [math]\frac{1}{3} \times 196[/math] as usual, but the [math]849\frac{1}{3}[/math] is using mixed number notation so it means [math]849 + \frac{1}{3}[/math].

I've never used this notation but when I was in primary school they certainly taught me to divide by whole numbers and note the remainder.
