8. Mrs. Reed bought 27 packs of cups, with 12 cups in each pack for a school picnic. There are 6 tables and Mrs. Reed will put the same number of cups on each table. Which equation could be used to find, c, the number of cups Mrs. Reed put on each table?

• A

  (27 × 12) ÷ 6 = c

• B

  (27 + 12) ÷ 6 = c

• C

  (27 × 12) – 6 = c

• D

  (27 – 12) ÷ 6 = c

9. Suzanna wrote this expression.

4 × (5 – 3) + (24 + 6) ÷ 3

Which statement is true about the parentheses in this expression?

• The parentheses indicate that 5 – 3 and then 24 + 6 should be solved first.

• The 4 × 5 should be solved first because these numbers come first in the expression.

• The parentheses indicate that 5 – 3 and then 24 + 6 should be solved after multiplying.

• The 6 ÷ 3 should be solved first because division should be the first operation.

10. Abby wants to simplify the expression shown.

6 × [(3.14 + 4.16) × 5 + 2]

What should be her first step?

• Multiply 6 by 3.14

• Add 3.14 and 4.16

• Add 5 and 2

• Multiply 4.16 by 5
