There is a lot of dust in Susie's house. It takes her 2 hours to vacuum the whole house. She can vacuum each room in 20 minutes. How many rooms does she have in her house?
Let's think: Susie spends 2 * 60 = 120 minutes vacuuming. Since she can vacuum each room in 20 minutes, she has 120 / 20 = 6 rooms in her house.. The answer is: 6.

Claudia has 122 ounces of water and is filling up cups. She has 8-ounce glasses, 5-ounce glasses, and 4-ounce glasses. If she fills six 5 ounce glasses and four 8 ounce glasses, how many 4 ounce glasses can she fill with the remaining water?
Let's think: She has used 32 ounces on 8 - ounce glasses because 4 x 8 = 32. She has used 30 ounces on the 5 - ounce glasses because 6 x 5 = 30. She has used 62 ounces in total because 32 + 30 = 62. She has 60 ounces left because 122 - 62 = 60. She can fill fifteen four - ounce glasses because 60 / 4 = 15.. The answer is: 15.

Ivanka wrote a book that took her 3 more months than it took Woody to write a book. Woody spent 1.5 years writing his book. How many months in total did Ivanka and Woody need to write their books?
Let's think: Woody = 1.5 years = 18 months. Ivanka = 18 + 3 = 21 months. 18 + 21 = 39 months. It took Ivanka and Woody 39 months to write their books.. The answer is: 39.

Mike and Leo have to print as many pamphlets as possible for a social gathering. Mike manages to print as fast as 600 pamphlets per hour for 9 consecutive hours. After a break, he resumes the task for another 2 hours achieving a third of the speed he was doing before. Leo, on the other hand, only works a third as many hours as Mike did before his break, but was twice as fast as Mike before he took his break. How many pamphlets do both manage to print at the end?
Let's think:
Mike printed before the break 600 pamphlets per hour * 9 hours = 5400 pamphlets. The working speed of Mike after the break was 600 pamphlets per hour / 3 = 200 pamphlets per hour. Mike printed after the break 200 pamphlets per hour * 2 hours = 400 pamphlets. Leo worked third of the time that Mike worked before the break, so he worked 9 hours / 3 = 3 hours. Leo worked twice as fast as Mike before his break 600 pamphlets per hour * 2 = 1200 pamphlets per hour. Leo printed 1200 pamphlets per hour * 3 hours = 3600 pamphlets. Combining the pamphlets of Leo and Mike 5400 + 400 + 3600 = 9400 pamphlets.. The answer is: 9400.
