In this lesson, you'll learn how to multiply FRACTIONS and MIXED NUMBERS.
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.
