Instructor Overview

Students explore methods of dividing a fraction by a fraction.

Key Concepts

Students extend what they learned in Lesson 4 to divide a fraction by any fraction. Students are presented with two general methods for dividing fractions:

  • Rewrite the dividend and the divisor so they have a common denominator. The answer to the original division will be the quotient of the numerators.
  • Multiply the dividend by the reciprocal of the divisor.

These two methods will work for all cases, including cases in which one or both of the numbers in the division is a fraction or whole number.

Goals and Learning Objectives

  • Use models and other methods to divide fractions by fractions.
