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 ?
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.
