Clue 5
Fractions of a number — the last clue
You calculate fractions of collected emeralds to narrow the search.
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
1/3 of 30 = ?
8/10 of 15 = ?
2/4 of 22 = ?
