The biggest trick is to find a common denominator (any common denominator will do).

Let's say we want to do 3/7 + 4/5.

Can we think of a number that can be divided into both sevenths and fifths?

That is 35.

Therefore, 3/7 = 15/35

4/5 = 28/35

Therefore, 3/7 + 4/5 = 15/35 + 28/35 = 43/35

Why should the denominators be the same? Because, having a common denominator makes it easy to add.

How much is 15 thirty-fifths + 28 thirty-fifths?

It's like asking, how much is 15 apples + 28 apples = 43 apples?

Therefore, 15 thirty-fifths + 28 thirty-fifths = 43 thirty-fifths = 43/35.

Hopefully, the following helps.
