Clue 5
Division facts (1-12) — the last clue
We need to split our search team into equal groups to cover the island. Let us divide the total number of agents.
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
22 ÷ 11 = ?
66 ÷ 11 = ?
36 ÷ 4 = ?
132 ÷ 11 = ?
88 ÷ 11 = ?
50 ÷ 10 = ?
33 ÷ 11 = ?
77 ÷ 11 = ?
6 ÷ 6 = ?
110 ÷ 10 = ?
44 ÷ 11 = ?
Step 2 — cross out the sentence with each answer
1.The villain escaped using a water jetpack, then fired a net launcher at the guards.
2.The villain sped down the river on a turbo surfboard, then launched decoy flares to distract us.
3.The villain soared over the jungle with a stealth glider, then activated sonar goggles in the dark.
