Clue 5
Division facts (1-12) — the last clue
The runaway bandit divided stolen gold coins equally into bags. Splitting the total gives us the final clue.
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
132 ÷ 11 = ?
88 ÷ 8 = ?
21 ÷ 7 = ?

4 ÷ 1 = ?
60 ÷ 10 = ?
72 ÷ 9 = ?
15 ÷ 3 = ?
7 ÷ 1 = ?
Step 2 — cross out the sentence with each answer
1.The villain blinded the temple guards with a flash lantern, then signaled distant airships with a silver whistle.
2.The villain created a thick haze using smoke bombs, then summoned a sudden squall with the storm pendant.
3.The villain swung across the ancient chasm with a grappling hook, then signaled distant airships with a silver whistle.
4.The villain snagged the vault key using a rope dart, then signaled distant airships with a silver whistle.
5.The villain swung across the ancient chasm with a grappling hook, then floated across the trap door using a cloud ring.
6.The villain soared over the temple walls using glider wings, then summoned a sudden squall with the storm pendant.
