Question

The ratio of catfish to trout in the local pond is 1 to 3. If there are 200 catfish in the pond, how many trout are there?

Answer 1

1 catfish : 3 trout
1 catfish x 200 : 3 trout x 200
200 catfish : 600 trout

Answer 2

Ratio of 1 to 3 means whenever there are 1 catfish, there are 1 x 3 = 3 trouts. so if there are 200 catfishes, 200 x 3 = 600 There are 600 trouts there :D
