Parts of a Fraction

Multiplying Fractions Steps: 1: Simplify first (if possible) 2: Then multiply numerators, and multiply denominators 3: Simplify again!!!

Multiplying Fractions Steps: 1: Divide common factors 2: Multiply numerators, and multiply denominators 3: Simplify! Ex 1:

Simplifying Before Multiplying Now, continue solving!

You try! Find each product. Simplify if possible 1) 2) 3)

When dividing rational numbers, remember: KEEP! CHANGE! FLIP! KEEP the first fraction. CHANGE the sign from division to multiplication. FLIP the second fraction.

Example 1: Find the Quotient KEEP! CHANGE! FLIP!

Example 2: Find the Quotient KEEP! CHANGE! FLIP!

You try! Find each quotient 1) 2) 3)

Practice Create 2 problems: one with multiplying fractions and one with dividing them. Exchange these problems with your partner and solve the problems!
