Clue 5
Fractions of a number — the last clue
A portion of the nectar supplies was consumed during the getaway. Find the fractional amount remaining to uncover final evidence.
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
3/8 of 24 = ?
2/5 of 10 = ?
1/10 of 110 = ?
1/6 of 12 = ?
1/2 of 14 = ?
5/10 of 2 = ?
5/10 of 12 = ?
1/2 of 20 = ?
2/6 of 15 = ?
3/4 of 4 = ?
1/5 of 40 = ?
Step 2 — cross out the sentence with each answer
1.The villain floated over security sensors using hover packs, then inspected silk threads with a magnifying visor.
2.The villain soared silently using solar sails, then distracted security guards using a nectar sprayer.
3.The villain swung from high rafters on silk cables, then sliced through mesh netting with silk cutters.
4.The villain slipped past thermal cameras in a thermal cloak, then created a pollen cloud using a pollen blower.
5.The villain slipped past thermal cameras in a thermal cloak, then illuminated dark corners with a uv flashlight.
6.The villain flew across the glass dome with glider wings, then created a pollen cloud using a pollen blower.
7.The villain floated over security sensors using hover packs, then sliced through mesh netting with silk cutters.
8.The villain slipped past thermal cameras in a thermal cloak, then distracted security guards using a nectar sprayer.
9.The villain floated over security sensors using hover packs, then distracted security guards using a nectar sprayer.
10.The villain flew across the glass dome with glider wings, then illuminated dark corners with a uv flashlight.
11.The villain soared silently using solar sails, then illuminated dark corners with a uv flashlight.
12.The villain soared silently using solar sails, then created a pollen cloud using a pollen blower.
