Question

The ratio of clown fish to angelfish at a pet store is 5:4. The ratio of angelfish to a goldfish is 4:3. There are 60 clown fish at the pet store. How many goldfish are there ?

Answer 1

60/5 = 12

From the ratio we know that 5:4 is clownfish to angel fish, therefore

12*4 = 48

There are 48 angel fish.

4 angelfish : 3 goldfish

48/4 = 12

12*3 = 36

48:36

There are 36 goldfish. Hope this helps!

Answer 2

Didn't you already ask this? Anyways, 
60/x = 5:4, x = 60/5 * 4, which gets us 48 for x.
There are 48 angelfish.
Then, using this, 
48:x = 4:3, x = 48/4 * 3, and this equals 36. 

Hope this helps and have a nice day:)
