Guoming has 120 fish. 3/8 of the fish are goldfish. 1/5 of them are angelfish and the rest are guppies. What fraction of the fish are guppies?

The answer in the book is 17/40.. but i couldn't get it.

thank you in advance.

Let's try:

One possible method:

Guoming has 120 fishes.

(3/8 of the fish are goldfish)

3/8 x 120 = 45 of the fish are goldfish.

(1/5 of them are angelfish)

1/5 x 120 = 24 of them are angelfish

(the rest are guppies)

guppies → 120 - 45 - 24 = 51

(What fraction of the fish are guppies?)

guppies/total → 51/120 →

**17/40**

Hope this helps

Cheers
