In a fish tank, 50% of the fish are clown fish, 1/3 are angel fish and the rest are goldfish. There are 33 clown fish in the fish tank. (b) How many goldfish are there in the fish tank?

11 gold fish

Step-by-step explanation:

We are told that

In a fish tank, 50% of the fish are clown fish and there are 33 clown fish in the fish tank.

Let the total number of fishes in the tank be = x

Hence,

50% of x = 33

50/100 × x = 33

50x/100 = 33

Cross Multiplying

50x = 33 × 100

x = 33 × 100/50

x = 66 fishes

Hence, the total number of fishes in the tank = 66 fishes

1/3 are angel fish

The number of angel fishes are

1/3 × 66 fishes = 22 angel fish

•The rest are goldfish. How many goldfish are there in the fish tank?

The number of gold fish is calculated as:

Total number of fishes -( Number of clown fish + Number of angel fish)

= 66 - (33 + 22)

= 66 - 55

= 11

Therefore, the number of gold fish is 11
