Five-eighths to add one-eighth equals six-eighths, equals three-quarters

Adding fractions with various Denominators

But what about when the denominators (the bottom numbers) are not the same?


3/8+1/4=?
+=
*
Three-eighths to add one-quarter equates to ... What?

We should somehow do the denominators the same.

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