user: [Question]There are 66 goats at a farm and twice as many chickens. If the number of ducks is half of the total of the goats and chickens, and the number of pigs is a third of the number of ducks, how many more goats are there than pigs?
[Answer]There are 66 x 2 = 132 chickens. There are 66 + 132 = 198 goats and chickens. There are are 198 / 2 = 99 ducks. There are 99 / 3 = 33 pigs. There are 66 - 33 = 33 more goats than pigs. The answer is 33.
Q: Fiona completed 36 math questions in an hour. Shirley was able to complete twice as many math questions within that same time, and Kiana completed half of the sum of Fiona and Shirley's math questions. If they each did the same number of questions the following hour, how many math questions did all three girls complete in 2 hours?
A: Shirley completed 36 x 2 = 72 questions. The sum of Fiona and Shirley's questions is 36 + 72 = 108. Kiana completed 108 / 2 = 54 questions. In one hour, they completed 108 + 54 = 162 questions. In two hours, they completed 162 x 2 = 324 questions. The answer is 324.
Question: Rhonda, Sally, and Diane are members of their school's track team. The three of them run the 600-meter relay race together. Rhonda runs the first 200 meters of the race, Sally runs the second 200 meters of the race, and Diane runs the final 200 meters of the race. Rhonda can run 200 meters in 24 seconds. Sally takes two seconds longer to run the same distance, while Diane can run 200 meters three seconds faster than Rhonda. How many seconds does it take for the three of them to run the 600-meter relay race?
Answer: Sally takes 24 + 2 = 26 seconds. Diane takes 24 - 3 = 21 seconds. Thus, the three take 24 + 26 + 21 = 71 seconds to run the 600 - meter relay race. The answer is 71.

Q: Edward the plumber is replacing a pipe in a bathroom wall. He needs to use 40 feet of copper pipe to complete the job. For every 5 feet of pipe, Edward must use one tightening bolt, and for every bolt, he uses two washers. He buys a bag of 20 washers for the job. After he completes the bathroom job, how many washers will be remaining in the bag?
A: If Edward needs to use 1 bolt per every five feet of piping, then for a job requiring 40 - feet of piping, he will use 40 / 5 = 8 tightening bolts. If for every 1 bolt he uses two washers, then he will need 8 * 2 = 16 washers to complete the job. if he buys a bag containing 20 washers, and removes 16, he will have 20 - 16 = 4 washers remaining in the bag. The answer is 4.
