Question: Penelope has 5 M&M candies for every 3 Starbursts candies. If she has 25 M&M candies, how many Starbursts candies does she have?
Answer: Let 5 M&M candies and 3 Starbursts candies be referred to as the unit amounts of each candy. 5 M&M candies make one unit so 25 makes 25 / 5 = 5 units of M&M candies. For every unit of 5 M&M candies, there is a corresponding unit of 3 Starbursts candies so for 5 units of M&M, she has 5 units of 3 Starbursts candies which is = 5 * 3 = 15 Starbursts candies. The answer is 15.
[Question]A giant spider is discovered. It weighs 2.5 times the previous largest spider, which weighed 6.4 ounces. Each of its legs has a cross-sectional area of .5 square inches. How much pressure in ounces per square inch does each leg undergo?
[Answer]The spider weighs 6.4 * 2.5 = 16 ounces. So each leg supports a weight of 16 / 8 = 2 ounces. That means each leg undergoes a pressure of 2 / .5 = 4 ounces per square inch. The answer is 4.
Q: Joyce, Michael, Nikki, and Ryn have a favorite movie. Joyce's favorite movie is 2 hours longer than Michael's movie. Nikki's movie is three times as long as Michael's movie, and Ryn's favorite movie is 4/5 times as long as Nikki's favorite movie. If Nikki's favorite movie is 30 hours long, calculate the total number of hours of their favorite movies together.
A: Since Nikki's favorite movie is 30 hours long, Ryn's favorite movie is 4 / 5 * 30 = 24 hours long. The total number of hours for Nikki's and Ryn's favorite movies is 24 + 30 = 54 hours long. Nikki's movie is also three times as long as Michael's favorite movie, meaning Michael's favorite movie is 30 / 3 = 10 hours long. Together, Nikki, Ryn, and Michael's favorite movies are 54 + 10 = 64 hours long. If Joyce's favorite movie is 2 hours longer than Michael's favorite movie, then her favorite movie is 10 + 2 = 12 hours long. The length of Nikki, Ryn, Michael, and Joyce's favorite movies is 64 + 12 = 76 hours. The answer is 76.
Question: TreShaun's full marker has enough ink in it to paint three 4 inch by 4 inch squares. If he colors in two 6 inch by 2 inch rectangles, what percentage of ink is left?
Answer: Each 4 by 4 square equals 16 square inches because 4 x 4 = 16. Three squares equals 48 square inches because 3 x 16 = 48. Each rectangle uses 12 square inches because 2 x 6 = 12. Both rectangles will use 24 square inches because 2 x 12 = 24. He has 1 / 2 of the ink left because 24 / 48 = 1 / 2. He has 50% of the ink left because 1 / 2 x 100 = 50. The answer is 50.
