Question: Jake makes a drink that is 2 parts Coke, 1 part Sprite and 3 parts Mountain Dew. If the drink contains 6 ounces of Coke, how many ounces is the drink?
Answer with step-by-step thinking: The drink is 2 + 1 + 3 = 6 parts. The drink is 2 / 6 = 1 / 3 coke. So the drink is 6 / (1 / 3) = 18 ounces.
So the answer is 18.

Question: Mr. Johnson has a prescription with enough pills for 30 days. After four-fifths of the days, he has 12 pills left. How many pills is Mr. Johnson supposed to take a day if he takes the same dose daily?
Answer with step-by-step thinking: Mr. Johnson has been taking the pills for 30 * 4 / 5 = 24 days. He has 30 - 24 = 6 days left to finish the pills. Thus, Mr. Johnson is supposed to take 12 / 6 = 2 pills a day.
So the answer is 2.

Question: Lady Bird uses 1 1/4 cup flour to make 9 biscuits. She's hosting this month's Junior League club which has 18 members and wants to make sure she allows 2 biscuits per guest. How many cups of flour will Lady Bird need?
Answer with step-by-step thinking:
There will be 18 members and she wants to allow 2 biscuits per member so that's 18 * 2 = 36 biscuits. Her biscuit recipe yields 9 biscuits and she needs to make 36 biscuits so she needs to make 36 / 9 = 4 batches of biscuits. 1 batch of biscuits uses 1 1 / 4 cup flour and she needs to make 4 batches so she will use 1.25 * 4 = 5 cups of flour.
So the answer is 5.
