Question: Three years ago, Bethany was twice the age of her younger sister. In 5 years, her younger sister will be 16. How old is Bethany now?
Answer: First find how old Bethany's sister currently is: 16 years - 5 years = 11 years. Then find how old her sister was 3 years ago: 11 years - 3 years = 8 years. Then double that age to find how old Bethany was three years ago: 8 years * 2 = 16 years. Then add 3 years to that number to find how old Bethany is now: 16 years + 3 years = 19 years. The answer is 19.

Question: Titan's father has an onion farm ready for harvest. He borrows Mr. Clay's pickup and transports the harvest to their store, carrying ten bags per trip, prepared for sale. If the onions are in 50 kgs bags, and the pickup makes 20 trips, what's the total weight of onions harvested by Titan's father?
Answer: On one trip, the pickup carries 10 bags * 50 kg / bag = 500kg of onions. After 20 trips, the total weight of onions transported to the store is 20 trips * 500 kg / trip = 10000 kgs. The answer is 10000.
[Question]Monica made cookies for herself and her family. Her father ate 10 cookies and her mother ate half as much as the father. Her brother ate 2 more than her mother. How many cookies are left for Monica if she made 30 cookies in total?
[Answer]Monica's mother ate half as many cookies as Monica's father, so she ate 10 cookies / 2 = 5 cookies. Monica's brother ate 5 cookies + 2 cookies = 7 cookies. There were 30 cookies - 7 cookies - 5 cookies - 10 cookies = 8 cookies left for Monica. The answer is 8.
[Question]In five years, Grant will be 2/3 the age of the hospital that he is hired into. If Grant is currently 25 years old, how old is the hospital now?
[Answer]
If Grant is currently 25 years old, he will be 25 + 5 = 30 years old in five years. If 2 / 3 represents Grant's age in five years, then the fraction representing the number of years the hospital is older than Grant is 1 - 2 / 3 = 1 / 3. If 2 / 3 represents 30 years, 3 / 3, which is the fraction representing the age of the hospital, represents 3 / 3 * 30 * 3 / 2 = 45 years. Currently, the hospital is 45 - 5 = 40 years old. The answer is 40.
