Question

how do you do fractions?

Answer 1

Meaning...

Answer 2

hey i am in 7th grade....and i never understood the simple steps!!

Answer 3

Wow...do you mean adding or subtracting or multiplying or dividing them?

Answer 4

all

Answer 5

O.K.

Answer 6

To add, you need to make common denominators (the bottom part) for both fractions

Answer 7

You following?

Answer 8

no .i am not stupid though.. can you show me a problem?

Answer 9

So, for 1/2 + 3/4, you need to get both to have a bottom of 4. That's a number that both 2 and 4 go into.

Answer 10

So you'd multiply 1/2 by 2/2, because to multiply fractions you just multiply the tops and bottoms, getting 2/4

Answer 11

And if you know simplifying fractions you know that 1/2 is the same as 2/4, so this always works

Answer 12

But you always need to multiply by 2/2 or 5/5 or whatever, because otherwise you're not multiplying by 1 (2/2 or 5/5 are both just 1)

Answer 13

Good so far?

Answer 14

yup..

Answer 15

So then, to add them you can just add the tops...BUT KEEP THE BOTTOM THE SAME.

Answer 16

So 1+2=3, so your answer is 3/4

Answer 17

wow i am very stupid... well thanks

Answer 18

Then, for subtraction, it's the same thing, except you subtract the top numbers instead of adding them (duh!)

Answer 19

Good?

Answer 20

yes

Answer 21

And then I showed you multiplication already (when you get common denominators)

Answer 22

So that leaves division.

Answer 23

You just reverse the second fraction and multiply them, so 1/2 divided by 3/4 would really just be 1/2 x 4/3

Answer 24

Which gives you 4/6, which you simplify into 2/3

Answer 25

You do know simplification of fractions, right?

Answer 26

Well, anyway, you just divide both the top and the bottom normally by a number they both go into.

Answer 27

Got all of that?

Answer 28

You there?
