To find the greatest number of treat bags Devon can make, we need to determine the greatest common divisor (GCD) of the number of stickers (25) and the number of pieces of fruit (15).
First, we can list the factors of each number:
- Factors of 25: 1, 5, 25
- Factors of 15: 1, 3, 5, 15
The common factors of 25 and 15 are 1 and 5. The greatest of these is 5.
Therefore, the greatest number of bags Devon can make, so that each cousin gets the same number of stickers and pieces of fruit, is 5 bags.
