The denominator stays the same. Step 4. Simplify! 6 x 2 + 2 = 14 = 7 6 6 3 Introduce Multiplying Fractions: To Multiply Fractions: Step 1. Multiply the numerators. Step 2. Multiply the denominators. Step 3. Simplify. Example: 3 x 6 = 18 = 1 4 9 36 2 Work in Class: a. 3 x 2 4 3 b. 2 x 3 5 9 c. 6 x 7 7 6 d. 12 x 4 15 10 e. 5 x 8 9 Extension: Multiplying Mixed Numbers / using operations / negative mixed numbers.
