In this lesson, students begin to synthesizing knowledge about multiplying and dividing decimals and fractions. They write word form expressions numerically. For example, "twice the sum of 3/5 and 1 1/2 is 2 x (3/5 + 1 1/2)". Then they write numerical expressions in word form. For example, 2/5 x (1/2 -0.4) is written as, "2/5 times the difference between 1/2 and 0.4".
