Final answer:
To find the total number of fish in the coral reef, multiply the number of groups of fish by the number of fish in each group.
Step-by-step explanation:
To find the total number of fish that live in the coral reef, you need to multiply the number of groups of fish by the number of fish in each group. In this case, there are 187 groups of fish and 12 fish in each group.
To calculate the total, you can use the multiplication operation: 187 groups * 12 fish = 2,244 fish.
Therefore, there are 2,244 fish that live in the coral reef.
