# Section B: Practice Problems Fractions of Whole Numbers

## Section Summary

Details

In this section, we explored the relationship between multiplication and division. We learned that 1 diagram can represent different multiplication and division expressions. For example, we can interpret this diagram with 4 different expressions:

•   because each rectangle is divided into 4 equal parts and three of them are shaded.

•   because there are 3 parts shaded and each one is of the rectangle.

•   because there are 3 rectangles and each one is divided into 4 equal parts.

•   because there are 3 rectangles and of each one is shaded.

We know that all of these expressions are equal because they all represent the same diagram. We can use any of these expressions to represent and solve this problem:

• Mai ate of a 3 pound bag of blueberries. How many pounds of blueberries did Mai eat?

## Problem 1 (Lesson 6)

Han cuts a 15-foot piece of rope into 4 equal parts. Decide whether each expression represents the length of each part of the rope in feet. Explain or show your reasoning.

## Problem 2 (Lesson 7)

Find the value of each expression.

## Problem 3 (Lesson 8)

Kiran ran the length of his road, which is 9 miles long.

1. How far did Kiran run?

2. Show or explain your thinking.
