Mabel is counting sharks in the ocean. She knows that of the fish that she sees, 25% will be sharks and 75% will be another type of fish. On day one she counts 15 fish. On day 2 she counts three times as many. How many sharks did she count over those two days?

How many fish did Mabel count on day 2? ** She counts 45 fish on day 2 because 3 x 15 = <<3*15=45>>45
How many fish did Mabel count in total? ** She counts 60 fish in total because 15 + 45 = <<15+45=60>>60
How many sharks did Mabel count? ** She counts 15 sharks because 60 x .25 = <<60*.25=15>>15
