Jen and Tyler are gymnasts practicing flips. Jen is practicing the triple-flip while Tyler is practicing the double-flip. Jen did sixteen triple-flips during practice. Tyler flipped in the air half the number of times Jen did. How many double-flips did Tyler do? Give the rationale and then the answer.
Let's think step by step. Jen did 16 triple - flips, so she did 16 * 3 = 48 flips. Tyler did half the number of flips, so he did 48 / 2 = 24 flips. A double flip has two flips, so Tyler did 24 / 2 = 12 double - flips.. The answer is: 12.

There are 20 stickers on a page. If you have 12 pages of stickers but lose one of the pages, then how many stickers would you have? Give the rationale and then the answer.
Let's think step by step. After losing one of the pages you have 12 - 1 = 11 pages of stickers. If each page has 20 stickers on it, you have 11 x 20 = 220 stickers.. The answer is: 220.

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? Give the rationale and then the answer.
Let's think step by step. 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.. The answer is: 16.
