3 over 7 and 2 over 5

2 over 5 and 3 over 4

3 over 7 and 2 over 9

Answer 1

This a bit trickier to figure out, do you know how to do long division?

Answer 2

no

Answer 3

Give me a second, I realized this is impractical to do via text, I'm gonna get my notebook out and work out explaining long division, one sec

Answer 4

I do not know how to do the latex so i will write it out and try to get uploaf he picture

Answer 5

^That's what I'm doing lol

Answer 6

Hush

Answer 7

ok

Answer 8

Wait, you don't need long division for this e.e
You just divide 1 by 3 for example
Repeating means it doesn't end so
1/3 would be .333333 etc
It goes on and on
Would you mind trying to divide the first one and see if you can do it?

Answer 9

That's why you need long division, otherwise it would be a calculator

Answer 10

Long division would allow you to get the decimal without a calculator

Answer 11

Some people can do it in their head hence why i asked e.e

Answer 12

whats the anwser

Answer 13

We can't just give you the answer, we have to try iur best to help you learn or you won't know how to do it when you need it

Answer 14

i have been

Answer 15

i only ask if i completely dont know

Answer 16

Alright, so the process of long division goes something like this, I'll give an example problem of say 3 divided by 8

First we do 3/8 and see how many times it goes into it, in this case it would be twice with 2 remainder, we then multiply 3 by 2 to get 6, and subtract that from 8, 3 doesn't go into 2 so we add a zero and bring it down, divide multiply subtract and brind down. That is the 4 steps of long division.

Answer 17

which i dont

Answer 18

That is what a repeating decimal looks like, it's stuck in a pattern it will never get out of

Answer 19

Does that make sense so far?
