Clue 5

Division facts (1-12) — the last clue

A group of stray kittens helped the thief. We divide up the stolen treats to see how many fish each kitten got.

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!
