In this video, we will learn how to divide fractions. We will begin by learning how to find the reciprocal of a number. This is done by interchanging the numerator and denominator. If we are given an integer we can first change it into a fraction by writing the integer over 1. We will then move into dividing fractions. This is done by multiplying the first fraction (leftmost) by the reciprocal of the second fraction (rightmost)
