[Question]Ron is part of a book club that allows each member to take a turn picking a new book every week. The club is made up of three couples and five single people along with Ron and his wife. How many times a year does Ron get to pick a new book?
[Answer]There are 3 couples in the club, so there are 3 * 2 = 6 people in couples in the club. Along with the singles and Ron and his wife, there are 6 + 5 + 2 = 13 people in the book club. There are 52 weeks in a year, so Ron gets to pick a new book 52 / 13 = 4 times a year. The answer is 4.

[Question]Jenny has a tummy ache. Her brother Mike says that it is because Jenny ate 5 more than thrice the number of chocolate squares that he ate. If Mike ate 20 chocolate squares, how many did Jenny eat?
[Answer]Thrice the number of chocolate squares that Mike ate is 20 squares * 3 = 60 squares. Jenny therefore ate 60 squares + 5 squares = 65 chocolate squares. The answer is 65.

[Question]Mr. Alonzo harvested 245.5 kg of tomatoes. He sold 125.5 kg to Mrs. Maxwell and 78 kg to Mr. Wilson. How many kilograms of tomatoes are not sold?
[Answer]Mr. Alonzo was able to sell 125.5 + 78 = 203.5 kg of tomatoes. So, there are 245.5 - 203.5 = 42 kg unsold tomatoes. The answer is 42.

[Question]George collected 50 marbles in white, yellow, green, and red. Half of them are white, and 12 are yellow. There are 50% fewer green balls than yellow balls. How many marbles are red?
[Answer]
Half of the marbles are white, so there are 50 / 2 = 25 white marbles. Green marbles are only 50% as many as yellow marbles, so there are 50 / 100 * 12 = 6 green marbles. So currently we know that we have 25 + 12 + 6 = 43 marbles. The rest are red, so there are 50 - 43 = 7 red marbles. The answer is 7.
