Clue 5

Fractions of a number — the last clue

Calculate the fraction of pit-stop fuel reserves left in the storage tank to reveal the last 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
2/6 of 27 = ?
3/6 of 4 = ?
2/4 of 8 = ?
1/6 of 42 = ?
1/5 of 25 = ?
4/6 of 9 = ?
2/4 of 24 = ?
1/10 of 110 = ?
3/8 of 8 = ?
4/6 of 12 = ?
1/8 of 80 = ?
Step 2 — cross out the sentence with each answer
1.The villain activated the nitro boost, then shot a grapple hook.
2.The villain executed a turbo drift, then sliced with a laser cutter.
3.The villain fired the jump jets, then launched a smoke screen.
4.The villain activated the nitro boost, then sliced with a laser cutter.
5.The villain executed a turbo drift, then deployed an emp blaster.
6.The villain raised a sonic shield, then shot a grapple hook.
7.The villain executed a turbo drift, then launched a smoke screen.
8.The villain fired the jump jets, then spilled an oil slicker.
9.The villain raised a sonic shield, then sliced with a laser cutter.
10.The villain fired the jump jets, then shot a grapple hook.
11.The villain activated the nitro boost, then deployed an emp blaster.
12.The villain raised a sonic shield, then deployed an emp blaster.
