Four in a Row: Fraction Addition and Subtraction

To add or subtract fractions, you must rewrite all the fractions with a common denominator. You may then add or subtract the numerators and place the result over the common denominator. Example: Add 3/5 + 5/16 and reduce to lowest terms. We need to first find a common denominator. In this case, the least common denominator will be 5 x 16 = 80. ................
