Division of Fractions

After learning multiplication of fractions, we now learn division of fractions. This series is composed only of two videos. The first video involves division of fractions improper fractions and the second video on mixed fractions. To divide fractions, you just have to get the reciprocal of the divisor and then multiply it by the dividend. The result is the answer of the division.

DF1 Division of Fractions (Proper and Improper)

This video is a tutorial on how to divide proper and improper fractions.

DF2 Division of Fractions (Mixed Fractions)

This video is a tutorial on how to divide mixed fractions by proper fractions, division of mixed fractions by mixed fractions, as well as division of mixed fractions by whole numbers.

In the next series, we will be learning about operations on decimals.
