![]() Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem. For example, use a visual fraction model to express 3 × (2/5) as 6 × (1/5), recognizing this product as 6/5. Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. Problem 3: Decompose to create equivalent fractions by drawing an area model and then dividing the area model into smaller parts. For example, use a visual fraction model to represent 5/4 as the product 5 × (1/4), recording the conclusion by the equation 5/4 = 5 × (1/4).ī. Problem 1: Use an area model to show that 3/4 6/8 Problem 2: Draw an area model to represent the equivalence of two fractions and express the equivalence as the sum and product of unit fractions. Understand a fraction a/ b as a multiple of 1/ b. Draw area models to represent number sentences and to prove fractions are equivalent. Use this principle to recognize and generate equivalent fractions. ![]() ![]() ![]() Engage NY Module 5 A-5 Decompose unit fractions using area models to show equivalence.
