Q: Cristine bought a dozen lemons and gave 1/4 of them to her neighbor. How many lemons does Cristine have left?
A: Cristine bought 1 x 12 = 12 lemons. She gave 12 x 1 / 4 = 3 lemons to her neighbor. So, Cristine is left with 12 - 3 = 9 lemons. The answer is 9.

Q: Marlon had 30 female baby bunnies in his hutch. They matured after four months, and he gave 2/5 of them to his friend Rodney. If after another three months the bunnies conceived and gave birth to 2 kittens each, calculate the total number of bunnies Marlon has in his hutch now.
A: When he gave Rodney 2 / 5 of the bunnies, he gave away 2 / 5 * 30 = 12 bunnies. He remained with 30 - 12 = 18 bunnies. When the bunnies gave birth to two kittens each, the total number of kittens born is 18 * 2 = 36. In total, Marlon now has 36 + 18 = 54 bunnies. The answer is 54.

Q: Ann is 6 years old. Her brother Tom is now two times older. What will be the sum of their ages 10 years later?
A:
Tom is currently two times older than Ann, which means he is 6 * 2 = 12 years old. In ten years Ann is going to be 6 + 10 = 16 years old. And Tom is going to be 12 + 10 = 22 years old. So the sum of their ages will be 16 + 22 = 38. The answer is 38.
