Question: Kim has 4 dozen shirts. She lets her sister have 1/3 of them. How many shirts does she have left?
Answer: She had 4 * 12 = 48 shirts to start with. She gives away 48 / 3 = 16. So she has 48 - 16 = 32 left. The answer is 32.

Question: Steve decides to read a new book. He reads 100 pages Monday, Wed, and Friday. The book is 2100 pages long. How many weeks does it take to read them all?

Question: Graeme is weighing cookies to see how many he can fit in his box. His box can only hold 40 pounds of cookies. If each cookie weighs 2 ounces, how many cookies can he fit in the box?
Answer: First find how many cookies are in a pound. 16 ounces per pound / 2 ounces / cookie = 8 cookies per pound. The box can hold 40 pounds, so 40 pounds * 8 cookies per pound = 320 cookies. The answer is 320.

Question: Annie is trying to figure out whether it's safe to drive her truck. For every 3 degrees the temperature drops below 32 degrees, Annie's chances of skidding on ice increase 5%. If she goes into a skid, she has a 40% of regaining control. Otherwise, she'll have a serious accident. If the temperature is 8 degrees, what is the percentage chance of Annie getting into a serious accident if she drives?
Answer:
First find how many degrees below 32 the temperature is: 32 degrees - 8 degrees = 24 degrees. Then divide that amount by the number of degrees per 5% increase in skid risk to find how many 5% increases there are: 24 degrees / 3 degrees / 5% increase = 8 5% increases. Multiply the number of increases by 5% to find the total increase in skid risk: 8 * 5% = 40%. Now find the chance that Annie has a serious accident if she goes into a skid by subtracting the chance she regains control from 100%: 100% - 40% = 60%. Finally, multiply the chance of going into a skid by the chance of having a serious accident after a skid to find the total risk of a serious accident: 60% * 40% = 24%. The answer is 24.
