Answer:

31/35

Step-by-step explanation:

So what we do is we need to convert them into something where we can combine them. The way you should do it is to convert the denominator by something they both share.

The closest one is 35 so multiply 3/5 by 7 and 2/7 by 5. Now you want to multiply the numerator by that number as well because it has to be equal.

You get 21/35 and 10/25, add them together to get 31/35.

Therefore, 31/35 is your answer.
