Questions 1–1 review Unit 1 (20%). The remaining 4 questions assess the current unit. Show your work, simplify exact answers, label units, and explain when asked.
Quiz
Begin with the review questions, then continue through the current-unit questions.
- Previous unit review
Use long division: 1,442 ÷ 7. Show the algorithm and check.
- Current unit
Calculate 3/2 × 3/4. Simplify.
- Current unit
Calculate 3 1/4 × 1 1/4. Simplify.
- Current unit
Draw a bar partitioned into 10 equal parts. Shade 7 parts. Circle groups of 3 parts. Use the model to find 7/10 ÷ 3/10. Explain the partial group.
- Current unit
Draw a bar partitioned into 4 equal parts. Shade 4 parts. Circle groups of 2 parts. Use the model to find 1 ÷ 1/2. Explain the partial group.

- 206
14 ÷ 7: write 2, subtract 14, remainder 0; bring down the next digit: 4 ÷ 7: write 0, subtract 0, remainder 4; bring down the next digit: 42 ÷ 7: write 6, subtract 42, remainder 0. Check: 7 × 206 = 1442.
- 9/8
3/2 × 3/4 = 9/8.
- 65/16
13/4 × 5/4 = 65/16.
- 7/3
Each small part is 1/10; 7 shaded parts divided into groups of 3 gives 7/3 = 7/3 groups.
- 2
Each small part is 1/4; 4 shaded parts divided into groups of 2 gives 4/2 = 2 groups.
