James and Lisa ordered 2 small pizzas. Each pizza has 6 slices. James ate 2/3 of all the slices. How many slices of pizza did James eat? Give the rationale and then the answer.
Let's think step by step. There are a total of 2 * 6 = 12 slices of pizza. Since James ate 2 / 3 of all the slices, he ate 2 / 3 * 12 = 8 slices of pizza.. The answer is: 8.

A clothing store has an inventory of 34 ties, 40 belts, 63 black shirts, and 42 white shirts. The number of jeans in the store is two-thirds of the sum of black and white shirts, and the number of scarves is half the number of the sum of ties and belts. How many more jeans are there than scarves? Give the rationale and then the answer.
Let's think step by step. The sum of black and white shirts is 63 + 42 = 105. The number of jeans in the store is (2 / 3) x 105 = 70. The sum of ties and belts is 34 + 40 = 74. The number of scarfs in the store is 74 / 2 = 37. There are 70 - 37 = 33 more jeans than scarfs in the store.. The answer is: 33.

Anna goes trick-or-treating in a subdivision where she gets 14 pieces of candy per house. Her brother Billy goes trick-or-tricking in a neighboring subdivision where he gets 11 pieces of candy per house. If the first subdivision has 60 houses and the second subdivision has 75 houses, how many more pieces of candy does Anna get? Give the rationale and then the answer.
Let's think step by step. First find the total number of pieces of candy Anna gets: 14 pieces / house * 60 houses = 840 pieces. Then find the total number of pieces of candy Billy gets: 11 pieces / house * 75 houses = 825 pieces. Then subtract the number of pieces Billy gets from the number Anna gets to find the difference: 840 pieces - 825 pieces = 15 pieces.. The answer is: 15.
