Q: 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?
A: 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: Unique is making biscuits. She has a sheet of dough that is 12 inches by 12 inches. She makes square biscuits and each biscuit is 3 inches by 3 inches. How many biscuits can she make with this dough?
Answer: She has 144 square inches of dough because 12 times 12 equals 144. Each biscuit uses 9 square inches of dough because 3 times 3 equals 9. She can make 16 biscuits because 144 divided by 9 equals 16. The answer is 16.
[Question]Dani brings two and half dozen cupcakes for her 2nd-grade class. There are 27 students (including Dani), 1 teacher, and 1 teacher’s aid. If 3 students called in sick that day, how many cupcakes are left after Dani gives one to everyone in the class?
[Answer]Dani brings 2.5 x 12 = 30 cupcakes. She needs this many cupcakes to feed everyone in class 27 + 2 = 29. With the 3 students calling in sick, there are this many people in class today 29 - 3 = 26. There are this many cupcakes left after everyone gets one 30 - 26 = 4 cupcakes. The answer is 4.
Q: Tom Sawyer has tricked his friends into whitewashing Aunt Polly's 100-foot fence. His first friend, Ben, whitewashed 10 feet. His second friend Billy whitewashed a fifth of the remaining fence. A third friend, Johnny, whitewashed a third of the fence that was left after that. How much of the fence still needs to be whitewashed?
A: It's a 100 - foot fence, and Ben whitewashed 10 feet, so there are 100 - 10 = 90 feet left after Ben is done. Billy whitewashed a fifth of that, or 90 / 5 = 18 feet. There is now 90 - 18 = 72 feet of fence left. Johnny whitewashes a third of that, or 72 / 3 = 24 feet. That leaves 72 - 24 = 48 feet of fence left to be whitewashed. The answer is 48.
Question: A typical tournament of tennis has 4 rounds. There are 8 games in the first round, 4 in the second round, 2 in the third round and 1 during the finals. If each game requires new tennis balls, and on average each game uses 5 cans of tennis balls, how many tennis balls in total are used at the end of the tournament if each can has 3 tennis balls?
Answer: There are a total of 8 + 4 + 2 + 1 = 15 games of tennis in a typical tournament. If 1 game uses 5 cans of tennis balls, then 15 games would use 15 * 5 = 75 cans of tennis balls. If 1 can of tennis balls has 3 balls, then 75 cans would have 225 balls. The answer is 225.
Q: When Michelle makes fresh pasta, she first makes the dough, then she rolls it out and cuts it, and then she hangs it on racks to dry for cooking later. She needs a drying rack for each three pounds of pasta she makes, and it takes two cups of flour to make each pound of pasta dough. She owns three racks right now. How many more drying racks will Michelle need if she makes pasta using three 8-cup bags of flour?
A:
Michelle used 3 * 8 = 24 cups of flour in the pasta dough. She made 24 / 2 = 12 pounds of pasta dough. She needs 12 / 3 = 4 drying racks for the pasta. Thus, Michelle needs 4 - 3 = 1 more drying rack. The answer is 1.
