  1. Multiply and DivideDecimals (C) Unit 6 Lesson 7

  2. Steps for Multiplying: • Take away the decimals from the problem. • Multiply or Divide like you would a whole number problem. • Count the amount of decimals to the right of each number in the original problem. • Insert your decimal that many places from the right in your answer.

  3. Example: 2.2 X 1.25 =

  4. Steps for Dividing: Once the problem is written correctly, the four steps for dividing are: • Move the outside decimal all the way to the right • Move the inside decimal to the right the same number of places as the outside decimal was moved • Raise the inside decimal straight up • Divide

  5. Example: 2.2 ÷ 1.25 = 1.25 2.0

  6. Choose the Answer: 93.7 × 8.1 = A. 7.5897 B. 758.97 C. 75.897 D. 7,589.7

  7. Choose the Answer: 345.56 ÷ 5.3 = A. 6,520 B. 65.2 C. 652 D. 6.52

  8. Estimate the product, then find the exact product. 5. 6 × 5.43 =

  9. Estimate the product, then find the exact product. 0.14 × 0.6 =

  10. Estimate the quotient, then find the exact product. 14 ÷ 25 =

  11. Estimate the quotient, then find the exact product. 7.2 ÷ 6 =

  12. Solve: 4.5 × 2.55 =

  13. Solve: 0.19 × 201.5 =

  14. Solve: 0.75 ÷ 375 =

  15. Solve: 4.08 ÷ 0.16 =

  16. Solve: 117.6 ÷ 2.1 =
