After Jeff comes by, Tim has 22 - 6 = 16 cans left. Tim buys 16 / 2 = 8 more cans. Tim has 16 + 8 = 24 cans in the end.
The answer: 24
Reverse engineering the question: Tim has 22 cans of soda. Jeff comes by, and takes 6 cans of soda from Tim. Tim then goes and buys another half the amount of soda cans he had left. How many cans of soda does Tim have in the end?

The chips were divided into 4 + 6 = 10 parts. Each part has 100 / 10 = 10 chips. Since Lyle owns 6 parts, then he has 6 x 10 = 60 chips. This is 60 / 100 x 100 = 60% of the entire chips.
The answer: 60
Reverse engineering the question: One hundred chips were divided by Ian and Lyle in the ratio 4:6. What percentage of the chips did Lyle have?

There are 3 + 2 = 5 kittens. If you originally had 2 cats then you now have 2 + 5 = 7 cats in total.
The answer: 7
Reverse engineering the question: My 2 cats had 3 female kittens and 2 male kittens. How many cats do I have in total?

7 leaves fell in the first hour. 4 leaves fell in the second hour. 4 leaves fell in the third hour. The total number of leaves that fell during the 3 hours is 7 + 4 + 4 = 15 leaves. The average number of leaves that fell per hour is 15 leaves / 3 hours = 5 leaves per hour.
The answer: 5
Reverse engineering the question:
