Clue 5
Division facts (1-12) — the last clue
The hacker dropped a big pack of cookies. We need to split them evenly among our group to get the 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
60 ÷ 12 = ?
20 ÷ 2 = ?
24 ÷ 3 = ?
4 ÷ 2 = ?
35 ÷ 5 = ?
66 ÷ 11 = ?
5 ÷ 5 = ?
108 ÷ 9 = ?
11 ÷ 1 = ?
108 ÷ 12 = ?
8 ÷ 2 = ?
Step 2 — cross out the sentence with each answer
1.The villain leaps high using a gravity coil, then tames a pet in adopt me.
2.The villain bounces around like a superball, then climbs the tower of hell.
3.The villain leaps high using a gravity coil, then climbs the tower of hell.
4.The villain dashes away with a speed coil, then tames a pet in adopt me.
5.The villain slashes the air with a sword of light, then climbs the tower of hell.
6.The villain bounces around like a superball, then tames a pet in adopt me.
7.The villain fires cheese from a pizza launcher, then climbs the tower of hell.
8.The villain leaps high using a gravity coil, then blends into hide and seek.
9.The villain bounces around like a superball, then survives a natural disaster.
10.The villain fires cheese from a pizza launcher, then blends into hide and seek.
11.The villain fires cheese from a pizza launcher, then breaks out of jailbreak.
12.The villain leaps high using a gravity coil, then survives a natural disaster.
