Clue 5

Division facts (1-12) — the last clue

We divided the camp keycards evenly among the search leaders so everyone could investigate the locked cabins.

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
12 ÷ 3 = ?
3 ÷ 1 = ?
80 ÷ 10 = ?

49 ÷ 7 = ?
24 ÷ 12 = ?
18 ÷ 3 = ?
66 ÷ 6 = ?
60 ÷ 12 = ?
24 ÷ 2 = ?
Step 2 — cross out the sentence with each answer
1.The villain dashed silently down the winding trail, then patched up a torn jacket using first aid skills.
2.The villain dashed silently down the winding trail, then tracked animal footprints in the mud.
3.The villain scouted the path using an expert map, then navigated by checking the night stars.
