Clue 5
Division facts (1-12) — the last clue
We find a heavy crate of space tools. We must split them equally to see how many were stolen.
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
28 ÷ 7 = ?
144 ÷ 12 = ?
28 ÷ 4 = ?
20 ÷ 10 = ?
55 ÷ 5 = ?
9 ÷ 1 = ?
12 ÷ 2 = ?
55 ÷ 11 = ?
40 ÷ 5 = ?
6 ÷ 2 = ?
110 ÷ 11 = ?
Step 2 — cross out the sentence with each answer
1.The villain used a jetpack boost to fly high, then spied the guards with a star scope.
2.The villain used a jetpack boost to fly high, then tightened a bolt with a space wrench.
3.The villain blocked the alarms with a force shield, then lighted the escape with a rocket flare.
4.The villain used a jetpack boost to fly high, then checked the path with an astro compass.
5.The villain sliced the door with a laser cutter, then lighted the escape with a rocket flare.
6.The villain sliced the door with a laser cutter, then recharged with a solar charger.
7.The villain blocked the alarms with a force shield, then spied the guards with a star scope.
8.The villain stomped past with gravity boots, then lighted the escape with a rocket flare.
9.The villain blocked the alarms with a force shield, then recharged with a solar charger.
10.The villain pulled the loot with a tractor beam, then lighted the escape with a rocket flare.
11.The villain blocked the alarms with a force shield, then checked the path with an astro compass.
12.The villain pulled the loot with a tractor beam, then spied the guards with a star scope.
