Clue 5
Division facts (1-12) — the last clue
A crate of glowing space crystals must be divided equally among the research labs. Split the total number of crystals evenly to power up the final decoder.
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
24 ÷ 2 = ?
8 ÷ 4 = ?
49 ÷ 7 = ?
77 ÷ 7 = ?
50 ÷ 5 = ?
30 ÷ 10 = ?
36 ÷ 9 = ?
15 ÷ 3 = ?
8 ÷ 8 = ?
48 ÷ 8 = ?
108 ÷ 12 = ?
Step 2 — cross out the sentence with each answer
1.The villain blocks all attacks with a force field, then cracks the vault code with a sonic decoder.
2.The villain blocks all attacks with a force field, then navigates the dark using a starlight sensor.
3.The villain stomps around in heavy gravity boots, then vanishes from sight using a stealth cloak.
4.The villain blocks all attacks with a force field, then escapes behind a bright solar shield.
5.The villain fires a glowing laser blaster, then escapes behind a bright solar shield.
6.The villain grabs the loot with a tractor beam, then freezes the locks with a cold ice ray.
7.The villain flies up high with a jetpack engine, then escapes behind a bright solar shield.
8.The villain fires a glowing laser blaster, then cracks the vault code with a sonic decoder.
9.The villain grabs the loot with a tractor beam, then navigates the dark using a starlight sensor.
10.The villain blocks all attacks with a force field, then vanishes from sight using a stealth cloak.
11.The villain grabs the loot with a tractor beam, then cracks the vault code with a sonic decoder.
