Clue 5
Division facts (1-12) — the last clue
Dividing the leftover plastic bricks equally into storage bins unlocked the final decoder key.
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
90 ÷ 9 = ?
96 ÷ 12 = ?
44 ÷ 11 = ?

77 ÷ 11 = ?
24 ÷ 2 = ?
36 ÷ 12 = ?
99 ÷ 9 = ?
36 ÷ 6 = ?
12 ÷ 12 = ?
Step 2 — cross out the sentence with each answer
1.The villain stacked studs to climb the wall, then scaled the tower with a suction cup.
2.The villain slid across smooth tiles, then signaled a getaway with a glow antenna.
3.The villain slid across smooth tiles, then escaped through a hinged hatch.
4.The villain flipped baseplates over, then swung away using a flexible hose.
5.The villain sorted bricks by shape, then scaled the tower with a suction cup.
6.The villain sorted bricks by shape, then escaped through a hinged hatch.
7.The villain sorted bricks by shape, then signaled a getaway with a glow antenna.
