[Question]: Kameron has 100 kangaroos on his large farm; Bert has 20 kangaroos on his farm. In how many more days will Bert have the same number of kangaroos as Kameron does now if he buys kangaroos at the same rate of 2 new kangaroos per day?
[Answer]: If Kameron has 100 kangaroos, he has 100 - 20 = 80 more kangaroos than Bert. Buying 2 kangaroos every day, it will take Bert 80 / 2 = 40 days to have the same number of kangaroos as Kameron has now.
So the answer is 40.

[Question]: Holly loves to drink chocolate milk. With breakfast, she drinks 8 ounces of chocolate milk before leaving for work. During her lunch break, she buys a new 64-ounce container of chocolate milk and then drinks 8 ounces of it. With dinner, she drinks another 8 ounces of chocolate milk. If she ends the day with 56 ounces of chocolate milk, how many ounces of chocolate milk did she begin the day with?
[Answer]: Before dinner, she had 56 + 8 = 64 ounces of CM. Before drinking 8 ounces of CM during lunch, she had 64 + 8 = 72 ounces of CM. Before buying 64 ounces of CM, she had 72 - 64 = 8 ounces of CM. And before breakfast, she had 8 + 8 = 16 ounces of chocolate milk.
So the answer is 16.

[Question]: Joy is winding balls of yarn for her cat to play with. The first ball is half the size of the second ball. The third ball is three times as large as the first ball. She used 27 feet of yarn for the third ball. How many feet of yarn did she use for the second ball?
[Answer]:
The first ball is a third of the size of the third ball, so it used 27 / 3 = 9 feet of yarn. The second ball is twice the size of the first ball, so she used 9 * 2 = 18 feet of yarn.
So the answer is 18.
