Let’s use blocks and diagrams to understand more about division with fractions.

Illustrative Math Unit 6.4, Lesson 5 (printable worksheets)

The following diagram shows more examples of how to solve problems that involve equal-sized groups that also involve fractions.

Write a fraction or whole number as an answer for each question. If you get stuck, use the fraction strips. Be prepared to share your strategy.

- How many ½s are in 2?
- How many ⅕s are in 3?
- How many ⅛s are in 1¼?
- 1 ÷ 2/6 = ?
- 2 ÷ 2/9 = ?
- 4 ÷ 2/10 = ?

Use the pattern blocks in the applet to answer the questions. (If you need help aligning the pieces, you can turn on the grid.)

- If the trapezoid represents 1 whole, what do each of the following shapes represent? Be prepared to show or explain your reasoning.

a. 1 triangle

b. 1 rhombus

c. 1 hexagon - Use pattern blocks to represent each multiplication equation. Use the trapezoid to represent 1 whole.

a. 3 · ⅓ = 1

b. 3 · ⅔ = 2 - Diego and Jada were asked “How many rhombuses are in a trapezoid?”

- Diego says, “1⅓. If I put 1 rhombus on a trapezoid, the leftover shape is a triangle, which is ⅓ of the trapezoid.”
- Jada says, “I think it’s 1⅓. Since we want to find out ‘how many rhombuses,’ we should compare the leftover triangle to a rhombus. A triangle is ⅓ of a rhombus.”

- Select all equations that can be used to answer the question: “How many rhombuses are in a trapezoid?”

a. ⅔ ÷ ? = 1

b. ? ÷ ⅔ = 1

c. 1 ÷ ⅔ = ?

d. 1 · ⅔ = ?

a. ? ÷ ⅔ = 1

For each situation, draw a diagram for the relationship of the quantities to help you answer the question. Then write a multiplication equation or a division equation for the relationship. Be prepared to share your reasoning.

- The distance around a park is 3/2 miles. Noah rode his bicycle around the park for a total of 3 miles. How many times around the park did he ride?
- You need ¾ yard of ribbon for one gift box. You have 3 yards of ribbon. How many gift boxes do you have ribbon for?

How many heaping teaspoons are in a heaping tablespoon? How would the answer depend on the shape of the spoons?

- Use the tape diagram to represent and find the value of ½ ÷ ⅓.

Mark up and label the diagram as needed. - What is the value of ½ ÷ ⅓? Use pattern blocks to represent and find this value. The yellow hexagon represents 1 whole. Explain or show your reasoning.

- Use a standard inch ruler to answer each question. Then, write a multiplication equation and a division equation that answer the question.

a. How many ½s are in 7?

b. How many ⅜s are in 6?

c. How many 5/10s are in 1⅞? - Use the tape diagram to represent and answer the question: How many ⅖s are in 1½?

Mark up and label the diagram as needed. - Write a multiplication equation and a division equation to represent each question, statement, or diagram.

a. There are 12 fourths in 3.

b. c. How many ⅔s are in 6?

d. - At a farmer’s market, two vendors sell fresh milk. One vendor sells 2 liters for $3.80, and another vendor sells 1.5 liters for $2.70. Which is the better deal? Explain your reasoning.
- A recipe uses 5 cups of flour for every 2 cups of sugar.

a. How much sugar is used for 1 cup of flour?

b. How much flour is used for 1 cup of sugar?

c. How much flour is used with 7 cups of sugar?

d. How much sugar is used with 6 cups of flour?
