Michael is baking a cake and needs 6 cups of flour. The only measuring cup he has is the 1/4 cup. He has an 8 cup bag of flour and realizes it would be faster to measure the flour he doesn't need, take it out of the bag, and then dump the rest of the bag into the bowl. How many scoops should he remove?
Let's think: He needs to remove 2 cups of flour because 8 minus 6 equals 2. He needs to use 8 scoops because 2 divided by .25 equals 8.. The answer is: 8.

There are 55 people at the track meet. 30 of them are boys, and the rest are girls. Three fifths of the girls have long hair, and the rest have short hair. How many girls have short hair?
Let's think: There are 55 - 30 = 25 girls at the track meet. There are (25 / 5) * 3 = 15 girls with long hair. There are 25 - 15 = 10 girls with short hair.. The answer is: 10.

A museum has eight different wings displaying four times as many artifacts as paintings displayed. Three of the wings are dedicated to paintings. The artifacts are divided evenly among the remaining wings. One painting is so large it takes up an entire wing, and the other two wings house 12 smaller paintings each. How many artifacts are in each artifact wing?
Let's think: The museum has 2 * 12 + 1 = 25 paintings displayed in the painting wings. There are 4 times as many artifacts displayed, so there are 25 * 4 = 100 artifacts. There are 8 wings and 3 are painting wings, so there are 8 - 3 = 5 artifact wings. Each artifact wing has 100 / 5 = 20 artifacts in it.. The answer is: 20.

Tom decides to renovate a house. There are 3 bedrooms and each bedroom takes 4 hours to renovate. The kitchen takes 50% longer than each bedroom. The living room took twice as much time as everything else combined. How long did everything take?
Let's think:
The kitchen took 4 * .5 = 2 hours longer than the bedrooms. So the kitchen took 4 + 2 = 6 hours. The bedrooms took 3 * 4 = 12 hours. So the kitchen and bedrooms combined took 12 + 6 = 18 hours. The living room took 18 * 2 = 36 hours. So everything took a total of 18 + 36 = 54 hours.. The answer is: 54.
