  3. 1030
  4. 215.04
  5. 29.9
  6. 2891

  8. 1/18
  9. 8
  10. 30
  11. 1000 × 3000 = 3000 and that is close to 1030, so my answer is reasonable.
  12. First I found common denominators for 7/8 and 2/3. 7/8 = 21/24 and 2/3 = 16/24. Then I added 721/24 + 516/24. 21/24 + 16/24 = 37/24 or 113/24. 7 + 5 + 113/24 = 1313/24.

V. Practice with Operations

Choose a strategy to solve each problem. Give any remainders as whole numbers. Use the pages in the Student Guide Reference section.

  1. 63 × 72 =
  2. 3089 × 8 =
  3. 3090 ÷ 3 =
  4. 178.24 + 36.8 =
  5. 0.65 × 46 =
  6. 17,346 ÷ 6 =
  7. 77/8 + 52/3 =
  8. 2/3 − 11/18 =
  9. 4/9 × 18 =
  10. 3/8 × 80 =
  1. Explain how to use estimation to make sure your answer to Question 3 is reasonable.
  2. Explain your strategy for solving Question 7.
