a. How many angel fish are there?
b. How many goldfish are there?

Answer 1

48 angel fish
36 goldfish

Answer 2

Answer:

(a)  Angel fish = 48

(b) Goldfish = 36

Step-by-step explanation:

The ratio of clown fish to angel fish at a pet store = 5:4

The ratio of angel fish to goldfish = 4:3

Using these ratios, we conclude that

Clown fish : Angel fish : Goldfish = 5:4:3

Let the number of Clown fish, Angel fish and Goldfish are 5x, 4x and 3x respectively.

There are 60 clown fish at the pet store.

$5x=60$

Divide both sides by 5.

$x=12$

The value of x is 12.

Angel fish : $4x=4(12)=48$

Goldfish : $3x=3(12)=36$

Therefore, the number of angel fish and goldfish are 48 and 36 respectively.
