Q: Fern buys one pair of high heels for $60 and five pairs of ballet slippers for 2/3rds of the price of the high heels. How much does she pay total?
A: First find the cost of one pair of ballet slippers: $60 * 2 / 3 = $40. Then find the total cost of the ballet slippers: $40 / pair * 5 pairs = $200. Then add that amount to the cost of the high heels to find the total cost: $200 + $60 = $260. The answer is 260.

Q: Max loves to play video games. He played for 2 hours on Wednesday and the same time on Thursday. On Friday his friends came to play together with him, so Max spent over three hours more on playing than on Wednesday. How many hours on average has Max spent playing video games during these three days?
A: Max played on Friday three hours more than on Wednesday, so he played for 2 + 3 = 5 hours. In total he played 2 + 2 + 5 = 9 hours. He was playing for three days, so on average, he spent 9 / 3 = 3 hours playing video games every day. The answer is 3.

Q: Martha met Ellen in the grocery store alone and asked her age. Martha realized she was twice as old as Ellen will be in six years. If Ellen is 10 years old now, calculate Martha's age now.
A:
In six years, Ellen will be 10 + 6 = 16 years old. If Martha is twice Ellen's age in six years, she is 2 * 16 = 32 years. The answer is 32.
