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? Give the rationale and then the answer.
Let's think step by step. 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.. The answer is: 15.

Bill started reading a book on the first day of April. He read 8 pages every day and by the 12th of April, he had covered two-thirds of the book. How many pages does the book have? Give the rationale and then the answer.
Let's think step by step. He read 8 pages every day for 12 days for a total of 8 * 12 = 96 pages. 96 pages is the same as two - thirds of the total number of pages which means: number of pages * (2 / 3) = 96. Therefore the total number of pages is 96 * (3 / 2) = 144 pages.. The answer is: 144.

There are 3 boxes of cereal. One box holds 14 ounces of cereal. Another box holds half the amount of the first box and 5 ounces less than the third box. How much cereal is there in all 3 cereal boxes? Give the rationale and then the answer.
Let's think step by step. First = 14 oz. Second = (1 / 2) * 14 = 7 oz. Third = 7 + 5 = 12 oz. 14 + 7 + 12 = 33 oz. There are 33 ounces of cereal in those 3 boxes.. The answer is: 33.
