Multiplying FRACTIONS involves three steps (analogous to waste management). However, steps 1 and 3 are sometimes unnecessary. 1. REDUCE: Cancel common factors, if any, from the numerator and the denominator. 2. REUSE: Multiply the reduced numbers, numerator to numerator and denominator to denominator. 3. RECYCLE: Change any improper fractions to mixed numbers. Examples: Multiplying MIXED NUMBERS involves the same three steps as above, but a preliminary step must be carried out—change any mixed numbers to improper fractions before proceeding.Below is a set of problems involving multiplying fractions and mixed numbers.
