In a fish tank, the ratio of goldfish to guppies is 2 to 4. there are a total of 12 fish in the fish tank. determine the number of goldfish in the fish tank.

4:8

Step-by-step explanation:

In order to get a total of 12, you have to multiply them by a specific number that adds up to 12. It is between 1-4. When you multiply both of them with all numbers 1-4, you find that the number 2 makes them equal to 2:4 and adds up to 12. 2 * 2 = 4 and 4 * 2 = 8. Therefore the answer is 4:8.
