Understand that multiplying a fraction by a/b means taking a parts of a decomposition of the fraction into b equal parts. 7. Understand that the area of a rectangle with side lengths a/b and c/d is the product a/b × p/q. This extends the area formula for rectangles to fractional side lengths, and also allows products of fractions to be represented visually as areas of rectangles. 10. Calculate products of fractions, and quotients of unit fractions and nonzero whole numbers (with either as divisor), and solve word problems involving these operations. Represent these operations using equations, area models and length models. 9. Understand division of unit fractions by whole numbers and division of whole numbers by unit fractions: a. Dividing a unit fraction 1/b by a whole number a results in a smaller unit fraction 1/a × b. (Using the inverse relationship between multiplication and division: 1/3 ÷ 2 = 1/6 because 1/6 × 2 = 1/3.) b. Dividing a whole number a by a unit fraction 1/b results in a greater whole number a × b. (Using the inverse relationship between multiplication and division: 2 ÷ 1/3 = 6 because 6 × 1/3 = 2.) TAKE A LOOK Multiply and divide fractions N.ME.05.12 Find the product of two unit fractions with small denominators using area model. N.MR.05.13 Divide a fraction by a whole number and a whole number by a fraction, using simple unit fractions.
