Clue 5
Division facts (1-12) — the last clue
We split the emergency oxygen canisters equally among the space crew. The leftover canisters gave 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
27 ÷ 9 = ?
16 ÷ 4 = ?
108 ÷ 12 = ?
7 ÷ 1 = ?
24 ÷ 4 = ?
36 ÷ 3 = ?
110 ÷ 11 = ?
11 ÷ 1 = ?
64 ÷ 8 = ?
24 ÷ 12 = ?
35 ÷ 7 = ?
Step 2 — cross out the sentence with each answer
1.The villain teleports instantly using an ender pearl, then activates a protective shield.
2.The villain digs rapidly with a diamond pickaxe, then hides the stolen loot in an ender chest.
3.The villain lays a trail of active redstone wiring, then activates a protective shield.
4.The villain digs rapidly with a diamond pickaxe, then activates a protective shield.
5.The villain hovers high with a noisy jetpack, then hides the stolen loot in an ender chest.
