Answer the following question.
Every day, Lou works out by running three miles on a circular track that is one-quarter of a mile long. His wife, Rosie, also runs on the same track at the same time as her husband, but she runs at twice the speed of her husband. During their workout, how many times does Rosie circle the track?
Step-by-step reasoning process: If Lou runs 3 miles during his workout on a track that is 1 / 4 miles long, then he circles the track 3 / (1 / 4) = 12 times. If Rosie runs twice as fast as Lou, then over the same time period, she runs 3 * 2 = 6 miles. If Rosie runs 6 miles on the 1 / 4 mile track, then she circles the track 6 / (1 / 4) = 24 times.
The answer is 24.

Answer the following question.
Jules is walking dogs to help pay for his family's vacation. The vacation costs $1,000. There are five members in his family and each one must contribute the same amount towards the vacation cost. He charges $2 to start a walk and $1.25 per block. If he walks 20 dogs, how many blocks in total does he have to walk them?
Step-by-step reasoning process: Jules has to earn $200 because 1000 / 5 = 200. He has earned $40 from starting the walks because 20 x 2 = 40. He has to earn $160 from distance, because 200 - 40 = 160. He has to walk 128 blocks because 160 / 1.25 = 128.
The answer is 128.

Answer the following question.
Ariel is collecting fish. She has 45 fish. 2/3 are male. How many female fish does she have?
Step-by-step reasoning process: 1 / 3 of her fish are female because 1 - (2 / 3) = 1 / 3. She has 15 female fish because 45 x (1 / 3) = 15.
The answer is 15.

Answer the following question.
There were sweets on the table. Jack came and took half of all the candies and 4 more candies. Then Paul came and took the remaining 7 sweets. How many sweets were on the table at first?
Step-by-step reasoning process: Jack took 4 more candies than the half, and Paul took the rest, which means 7 + 4 = 11 candies were half of all candies. That means at first there were 11 * 2 = 22 candies.
The answer is 22.
