Q: Henri has 8 hours to watch movies and read. He watches one movie that is 3.5 hours and one movie that is 1.5 hours. He then decides to read. If he can read 10 words a minute, how many words does he read before his free time is up?
A: He has 3 hours to read because 8 - 3.5 - 1.5 = 3. He has 180 minutes to read because 3 x 60 = 180. He can read 1,800 words because 180 x 10 = 1,800. The answer is 1800.
Question: Gail has two fish tanks. The first tank is twice the size of the second tank. There are 48 gallons of water in the first tank. She follows the rule of one gallon of water per inch of fish. If she keeps two-inch fish in the second tank and three-inch fish in the first tank, how many more fish would Gail have in the first tank than the second tank if one of the first tank fish eats another?
Answer: The second tank is 48 / 2 = 24 gallons. Following her rule, Gail keeps 24 / 2 = 12 two - inch fish in the second tank. She keeps 48 / 3 = 16 fish in the first tank. If one fish in the first tank ate another, she would have 16 - 1 = 15 fish in the first tank. Thus, Gail would have 15 - 12 = 3 more fish in the first tank. The answer is 3.

Question: Jonas is trying to expand his wardrobe. He has 20 pairs of socks, 5 pairs of shoes, 10 pairs of pants and 10 t-shirts. How many pairs of socks does he need to buy to double the number of individual items in his wardrobe?
Answer: First, we must recognize that all pairs of shoes and socks are actually two items each, whereas the pants and the t - shirts are individual items. Therefore there are 20 * 2 = 40 individual socks in 20 pairs of socks. Similarly, there are 5 * 2 = 10 individual shoes in 5 pairs of shoes. Therefore, Jonas has 40 + 10 + 10 + 10 = 70 individual items in his collection. To double this number, we perform 70 * 2 = 140. This means we need 140 - 70 = 70 new items to double the size. Since there are 2 individual socks in each pair, we take 70 / 2 = 35 new pairs of socks. The answer is 35.
