Q: Every time Janet folds her blanket its thickness doubles. If it starts out 3 inches thick, how thick will it be after 4 foldings?
A: First find how thick the blanket will be after 1 folding: 3 inches * 2 = 6 inches. Then find how thick the blanket will be after 2 foldings: 6 inches * 2 = 12 inches. Then find how thick the blanket will be after 3 foldings: 12 inches * 2 = 24 inches. Then find how thick the blanket will be after 4 foldings: 24 inches * 2 = 48 inches. The answer is 48.
Question: Socorro is preparing for a math contest. She needs to train for a total of 5 hours. Each day, she answers problems about multiplication for 10 minutes and then division problems for 20 minutes. How many days will it take for her to complete her training?
Answer: Socorro trains for a total of 10 + 20 = 30 minutes each day. She needs to train for a total of 5 x 60 = 300 minutes since an hour has 60 minutes. Therefore, she will complete her training in 300 / 30 = 10 days. The answer is 10.
[Question]Susan had a sum of money. She spent 1/5 of it in September, 1/4 of it in October, and $120 in November. After spending these amounts of money, she still had $540 left. How much money did she have at first?
[Answer]Let X be the amount Susan had originally. Susan spent 1 / 5 * X in September, 1 / 4 * X in October, and $120 in November. Susan has X - 1 / 5 * X - 1 / 4 * X - $120 = $540 left. Combining like terms, we get 11 / 20 * X - $120 = $540. Adding $120 to both sides, we get 11 / 20 * X = $660. Dividing both sides by 11 / 20 we get X = $1200. The answer is 1200.
Q: There are four growing trees. The first tree grows 1 meter/day, the second grows the same amount in half the time, the third grows 2 meters/day, and the fourth tree grows a meter more than the third each day. How many meters did the trees grow in total in 4 days?
A: The second tree grows 1 * 2 = 2 meters a day. The fourth tree grows 2 + 1 = 3 meters a day. The first tree grows 4 * 1 = 4 meters in 4 days. The second tree grows 2 * 4 = 8 meters in 4 days. The third tree grows 2 * 4 = 8 meters in 4 days. The fourth tree grows 3 * 4 = 12 meters in 4 days. In 4 days, all four trees grew 4 + 8 + 8 + 12 = 32 meters combined. The answer is 32.
Question: Ms. Alice can grade 296 papers in 8 hours. How many papers can she grade in 11 hours?
Answer: First you must recognize that the problem involves finding the rate of how fast Ms. Alice can grade papers. To find how many papers she can grade in 11 hours, it would be useful to first find out how many papers she can grade in one hour. To do so, divide 296 papers by 8 hours, 296 / 8, to get 37. Therefore, Ms. Alice can grade 37 papers in one hour. To find out how many papers she can grade in 11 hours, multiply the number of papers she can grade in one hour by 11. 37 * 11 gives you 407. Ms. Alice can grade 407 papers in 11 hours. The answer is 407.
Q: TreShawn's mom needs to order pizza for her son and his two friends. She knows that TreShawn always eats 1/2 a pizza. His friend Michael eats 1/3 of a pizza and his other friend LaMar eats 1/6 of a pizza. How many pizzas does she need to order?
A:
Half a pizza is the same as 3 / 6 of a pizza. 1 / 3 of a pizza is the same as 2 / 6 of a pizza. 3 / 6 of a pizza plus 2 / 6 of a pizza plus 1 / 6 of a pizza equals 6 / 6 of a pizza. Therefore, she needs to buy one pizza because 6 / 6 equals 1. The answer is 1.
