Answer:
- Divide the coins into three groups: two groups of 3 and one group of 2.
- Weigh the two groups of 3 coins.
- If one side is heavier, the heavier coin is in that group.
- If they balance, the heavier coin is in the group of 2.
- Weigh two coins from the heavier group (whether it’s 3 or 2 coins) to find the heaviest one.
