What fraction of the fish are goldfish?

How many goldfish does the pet store have?
goldfish

Answer 1

The number of gold fish is 60.

Answer 2

150 divided by 5 = 30
We do this because the ratio numbers add up to 5
Then there are 2 on one side which would be 2 x 30 = 60
Then there are 3 on the other side which would be 3 x 30 = 90
But since we only want the number of goldfish the answer would be 60,
And 60 is 60/150 which simplifies to 2/5 of the fish are gold fish

Answer: 60 goldfish and 2/5 of the fish are goldfish
