Clue 5
Division facts (1-12) — the last clue
Agent Ray divided the decrypted log files equally among the scanner stations to decode 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
120 ÷ 10 = ?
84 ÷ 12 = ?
55 ÷ 5 = ?
10 ÷ 2 = ?
16 ÷ 2 = ?
22 ÷ 11 = ?
8 ÷ 2 = ?
110 ÷ 11 = ?
36 ÷ 6 = ?
63 ÷ 7 = ?
6 ÷ 6 = ?
Step 2 — cross out the sentence with each answer
1.The villain warped the gravity grid, then sped away on a comet thruster.
2.The villain sliced through the vault lock, then glided clear using a solar sail.
3.The villain blinded the sensor turrets, then snagged the cargo using a tractor beam.
4.The villain blocked incoming transmissions, then deflected defenses with asteroid armor.
5.The villain blinded the sensor turrets, then sped away on a comet thruster.
6.The villain blasted past security doors, then sped away on a comet thruster.
7.The villain sliced through the vault lock, then deflected defenses with asteroid armor.
8.The villain blasted past security doors, then glided clear using a solar sail.
9.The villain blocked incoming transmissions, then glided clear using a solar sail.
10.The villain blocked incoming transmissions, then snagged the cargo using a tractor beam.
11.The villain warped the gravity grid, then snagged the cargo using a tractor beam.
12.The villain blasted past security doors, then deflected defenses with asteroid armor.
