Dividing Fractions Lesson 5-3
To Divide Fractions: Rewrite the first fraction. Change the division sign to a multiplication sign. Flip the second fraction upside down. Multiply.
Reciprocal When you flip the second fraction, you are writing that fractions reciprocal. 3 5 5 3
Example 1 1 3 ÷ 1 2 Rewrite: 1 3 x 2 1 = 2 3
Example 2 4 5 ÷ 4 9 Rewrite: 4 5 x 9 4 1 1 = 9 5 = 1 4 5
Example 3 12 ÷ 3 5 1 Rewrite: 12 1 x 5 3 4 1 = 20 1 =
Example 4 1 6 ÷ 2 1 Rewrite: 1 6 x 1 2 = 1 12
