Clue 5
Division facts (1-12) — the last clue
The local sky-scouts need to divide their map pieces equally among the team. Help them share the pieces to uncover 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
30 ÷ 5 = ?
6 ÷ 6 = ?
56 ÷ 8 = ?

60 ÷ 12 = ?
27 ÷ 9 = ?
108 ÷ 9 = ?
28 ÷ 7 = ?
66 ÷ 6 = ?
120 ÷ 12 = ?
Step 2 — cross out the sentence with each answer
1.The villain stomped up the metal wall using magnetic boots, then bounced off the balcony on a bungee rope.
2.The villain swung away using a grappling hook, then trapped the sky patrol using a net launcher.
3.The villain vanished into a cloud of smoke bombs, then trapped the sky patrol using a net launcher.
