Another example:

5/8 +1/8 =6/8 =3/4

Adding fractions with different Denominators

But what around when the denominators (the bottom numbers) space not the same?

Three-eighths to add one-quarter equals ... What?

We should somehow do the platform the same.

In this instance it is easy, because we understand that 1/4 is the exact same as 2/8 :
