Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:

She counts 45 fish on day 2 because 3 x 15 = 45. She counts 60 fish in total because 15 + 45 = 60. She counts 15 sharks because 60 x .25 = 15. Final answer: 15.
