Clue 5
Division facts (1-12) — the last clue
Dividing the encrypted memory blocks equally across the mainframe exposes the villain final identity.
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
70 ÷ 7 = ?
24 ÷ 8 = ?
48 ÷ 4 = ?
9 ÷ 9 = ?
45 ÷ 9 = ?
40 ÷ 5 = ?
11 ÷ 1 = ?
40 ÷ 10 = ?
108 ÷ 12 = ?
54 ÷ 9 = ?
6 ÷ 3 = ?
Step 2 — cross out the sentence with each answer
1.The villain overrode the sonic frequencies, then engaged a thermal vision cloak.
2.The villain took over the dronenet, then deployed magnetic shielding.
3.The villain overrode the sonic frequencies, then activated stealth camouflage.
4.The villain jammed the laser grid, then engaged a thermal vision cloak.
5.The villain triggered a cyber emp surge, then engaged a thermal vision cloak.
6.The villain took over the dronenet, then latched grappling cables.
7.The villain triggered a cyber emp surge, then deployed magnetic shielding.
8.The villain spoofed the holograms, then deployed magnetic shielding.
9.The villain overrode the sonic frequencies, then deployed magnetic shielding.
10.The villain spoofed the holograms, then fired overclocked thrusters.
