Q: Jerry is refilling the duck pond in his backyard during a drought. The pond can hold 200 gallons of water. Jerry's hose can normally pump 6 gallons/minute, but due to drought restrictions, it can only pump 2/3rds as fast right now. How many minutes will it take Jerry to fill his pond?
A: First find the current rate the hose pumps by multiplying its normal rate by 2 / 3: 6 gallons / minute * 2 / 3 = 4 gallons / minute. Then divide the number of gallons in the pond by the number of gallons pumped each minute to find how many minutes filling the pond takes: 200 gallons / 4 gallons / minute = 50 minutes. The answer is 50.
Question: Valerie’s cookie recipe makes 16 dozen cookies and calls for 4 pounds of butter. She only wants to make 4 dozen cookies for the weekend. How many pounds of butter will she need?
Answer: Her original recipe makes 16 dozen and she only needs 4 dozen so she needs to reduce the recipe by 16 / 4 = 4. For 4 dozen cookies, she needs to reduce her recipe by 4 and the original called for 4 pounds of butter so she now needs 4 / 4 = 1 pound of butter. The answer is 1.

Q: Baseball season opened up with the Chicago Cubs at home at Wrigley Field. They scored 2 home runs in the third inning, 1 home run in the fifth inning and 2 more home runs in the eighth inning. Their opponents, the Cardinals, scored 1 home run in the second inning and 1 home run in the fifth inning. How many more home runs did the Chicago Cubs score than the Cardinals in the game?
A: The Chicago Cubs scored 2 home runs in the third inning, 1 home run in the fifth inning, and 2 home runs in the eighth for a combined total of 2 + 1 + 2 = 5 home runs for the game. The Cardinals scored 1 home run in the second inning and 1 home run in the fifth inning for a combined total of 1 + 1 = 2 home runs for the game. If the Chicago Cubs scored a total of 5 home runs in the game and the Cardinals scored a total of 2 home runs in the games then 5 - 2 = 3 more home runs were scored by the Chicago Cubs than the Cardinals in the game. The answer is 3.
Question: John started weightlifting when he was 16. When he first started he could Clean & Jerk 80 kg and he could Snatch 50 kg. He manages to double his clean and jerk and increase his snatch by 80%. What is his new combined total lifting capacity?
Answer: His clean and jerk goes to 80 * 2 = 160 kg. His snatch increases by 50 * .8 = 40 kg. So his snatch is now 50 + 40 = 90 kg. So his total is 160 + 90 = 250 kg. The answer is 250.
