4. Round one: Express the missing divisor using a power of 10
6.76 ÷ ____ = .676
7,509 ÷ ____ = 75.09
432 ÷ ____ = .0432
89.3 ÷ ____ = .0893
62,195 ÷ ____ =

5. Round one: ANSWERS Express the missing divisor using a power of 10
6.76 ÷ 101 = .676
7,509 ÷ 102 = 75.09
432 ÷ 104 = .0432
89.3 ÷ 103 = .0893
62,195 ÷ 102 =

6. Round two: Estimate the quotient by rounding. (Do not solve)
EXAMPLE: ÷ 35 → ÷ 40 = 4
552 ÷ 85
141 ÷ 73
241 ÷ 58
799 ÷ 99
635 ÷ 95

7. Round two: ANSWERS Estimate the quotient by rounding. (Do not solve)
EXAMPLE: ÷ 35 → ÷ 40 = 4
552 ÷ 85 → 540 ÷ 90 = 6
141 ÷ 73 → 140 ÷ 70 = 2
241 ÷ 58 → 240 ÷ 60 = 4
799 ÷ 99 → 800 ÷ 100 = 8
635 ÷ 95 → 600 ÷ 100 = 6

8. Round Three: Both of these problems have a quotient of 6 and a remainder of 12. Prove that these two division problems are not equal.
156 ÷ 24
102 ÷ 15

9. Round Three: ANSWERS Both of these problems have a quotient of 6 and a remainder of 12. Prove that these two division problems are not equal.
156 ÷ 24 = 6.5
102 ÷ 15 = 6.8

10. Round Four: Divide
15.6 ÷ 15
68.25 ÷ 65
÷ 28

11. Round Four: ANSWERS Divide
15.6 ÷ 15 = 1.04
68.25 ÷ 65 = 1.05
÷ 28 = 20.06

12. Round Five: Solve the word problem
Dr. Felix uses 12 fluid ounces of detergent each week. If there are 87 fluid ounces of detergent in the bottle, in how many weeks will she need to buy a new bottle of detergent?

13. Round Five: ANSWERS Solve the word problem
Dr. Felix uses 12 fluid ounces of detergent each week. If there are 87 fluid ounces of detergent in the bottle, in how many weeks will she need to buy a new bottle of detergent?
Answer: 87 ÷ 12 – 7.25
Dr. Felix will need to buy a new bottle of detergent every 7 weeks.
