What does it mean to have unlike denominators?

Back

Unlike denominators are when the bottom numbers of two or more fractions are different.

How do you add fractions with unlike denominators?

Back

To add fractions with unlike denominators, first find the least common multiple (LCM) of the denominators, convert the fractions to equivalent fractions with the LCM as the new denominator, and then add the numerators.
