Objective: Represent the multiplication of n times a/b as (n × a)/b using the associative property and visual models.
Topic G extends the concept of representing repeated addition as multiplication, applying this familiar concept to work with fractions. Multiplying a whole number times a fraction was introduced in Topic A as students learned to decompose fractions. In Lessons 35 and 36, students use the associative property, as exemplified below, to multiply a whole number times a mixed number.
