Clue 5

Division facts (1-12) — the last clue

We share a bag of chew bones equally among the search dogs. Dividing the treats fairly gives us the final clue to stop them.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

55 ÷ 11 = ?

36 ÷ 3 = ?

7 ÷ 7 = ?

44 ÷ 4 = ?

108 ÷ 12 = ?

49 ÷ 7 = ?

48 ÷ 8 = ?

24 ÷ 6 = ?

48 ÷ 6 = ?

24 ÷ 12 = ?

80 ÷ 8 = ?

Step 2 — cross out the sentence with each answer

1.The villain followed a faint scent, then carried three bones at once.

2.The villain leaped over the barrier, then carried three bones at once.

3.The villain carried the prize away, then unlatched the backyard gate.

4.The villain followed a faint scent, then scaled the wooden fence.

5.The villain dashed across the lawn, then scaled the wooden fence.

6.The villain carried the prize away, then burrowed under the porch.

7.The villain barked a loud warning, then unlatched the backyard gate.

8.The villain dashed across the lawn, then snagged a flying disc.

9.The villain barked a loud warning, then carried three bones at once.

10.The villain leaped over the barrier, then scaled the wooden fence.

11.The villain dashed across the lawn, then carried three bones at once.
