Clue 5
Division facts (1-12) — the last clue
We found a bag of sky-rubies dropped by the suspect. If we divide the gems equally among our crew members, the leftover count will reveal 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
6 ÷ 6 = ?
48 ÷ 6 = ?
2 ÷ 1 = ?

90 ÷ 9 = ?
24 ÷ 2 = ?
45 ÷ 9 = ?
42 ÷ 7 = ?
Step 2 — cross out the sentence with each answer
1.The villain measured the air pressure with a steam barometer, then vanished behind a thick smoke screen.
2.The villain scanned the horizon with a brass spyglass, then drifted away on glider wings.
3.The villain measured the air pressure with a steam barometer, then escaped by firing a grappling hook.
4.The villain checked the flight time with a silver chronometer, then blasted a path with a harpoon gun.
5.The villain measured the air pressure with a steam barometer, then zoomed off using a steam booster.
6.The villain checked the flight time with a silver chronometer, then escaped by firing a grappling hook.
7.The villain checked the flight time with a silver chronometer, then vanished behind a thick smoke screen.
