Hint 3 of 3
Move kangaroos one at a time from the crowded park until both parks match.
Show solution
Approach: share the kangaroos fairly between the two parks
- Count: the left park has 13 kangaroos and the right park has 3, which is 16 kangaroos in all.
- Sharing 16 fairly means 8 in each park.
- The right park needs 5 more to reach 8, so move 5 kangaroos over — now both parks have 8.
