14 Objective: To add and subtract fractions with unlike denominators.

15 Add and Subtract Unlike Fractions Before you can add or subtract unlike fractions, rename one or both of the fractions so they have the same denominator.

16 Add and Subtract Unlike Fractions Before you can add or subtract unlike fractions, rename one or both of the fractions so they have the same denominator. This same denominator is called the common denominator.
