Answer:
There are 6 goldfish in each of the 3 aquariums at Joe's fish store.
Explanation:
To find out how many goldfish are in each aquarium, we can divide the total number of goldfish by the number of aquariums:
- 18 goldfish ÷ 3 aquariums = 6 goldfish per aquarium
Therefore, there are 6 goldfish in each of the 3 aquariums at Joe's fish store.
