Noah has two closets. Each closet can fit 1/4 as much as Ali's closet, which can fit 200 pairs of jeans. How many jeans can both Noah’s closets fit? Give the rationale and then the answer.
Let's think step by step. Each of Noah’s closets can fit 200 * 1 / 4 = 50 pairs of jeans. Combined, both his closets can fit 50 * 2 = 100 pairs of jeans.. The answer is: 100.

A swimming pool is being emptied through a drain at the bottom of the pool and filled by a hose at the top. The drain can empty the pool in 4 hours and the hose can fill the pool in 6 hours. The pool holds 120 liters of water. If the pool starts filled with water, how much water will be left after 3 hours? Give the rationale and then the answer.
Let's think step by step. It takes the drain 4 hours to empty the pool, so it drains at a rate of 120 liters / 4 hours = 30 liters / hour. After 3 hours, the drain will have removed 3 * 30 = 90 liters of water from the pool. It takes the hose 6 hours to fill the pool, so it fills at a rate of 120 liters / 6 hours = 20 liters / hour. After 3 hours, the hose will have added 3 * 20 = 60 liters of water to the pool. After 3 hours, there will be 120 liters + 60 liters – 90 liters = 90 liters of water left in the pool.. The answer is: 90.

John with his five friends ordered 3 pizzas. Each pizza had 8 slices. If they all finished and ate the same amount of pizzas, how many slices did each person eat? Give the rationale and then the answer.
Let's think step by step. There were 3 x 8 = 24 slices of pizza. Since there were 6 persons, then each person ate 24 / 6 = 4 slices.. The answer is: 4.
