Clue 5

Division facts (1-12) — the last clue

Dividing liquid chemical samples evenly among remaining test stations gives 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
77 ÷ 11 = ?
77 ÷ 7 = ?
80 ÷ 10 = ?
36 ÷ 4 = ?
36 ÷ 6 = ?
35 ÷ 7 = ?
6 ÷ 3 = ?
3 ÷ 3 = ?
24 ÷ 6 = ?
12 ÷ 1 = ?
110 ÷ 11 = ?
Step 2 — cross out the sentence with each answer
1.The villain disrupted the sonic frequency, then projected a hologram clone.
2.The villain reversed the gravity field, then fled using rocket boosters.
3.The villain zapped the particle core, then projected a hologram clone.
4.The villain zapped the particle core, then scanned for high temperatures.
