This document explains how to multiply fractions. It shows that when multiplying fractions, the sizes of the fractional parts change rather than staying the same size as with addition and subtraction. Examples are provided of multiplying different fractions like 1/2 x 1/2 = 1/4, 1/2 x 3/4 = 3/8, and 2/3 x 4/5 = 8/15. Practice problems are also given for the student to try multiplying different fractions.
