Question: Jasmine wants to organize her books in order of most number of pages to least number of pages. Jasmine's longest book has 396 pages and her shortest book has one-fourth as many pages as the longest. If the book in the middle of her shelf has three times the number of pages of the shortest book, then how many pages does the middle book have?
Answer: Step-by-step reasoning process: Jasmine's shortest book is 1 / 4 * 396 pages = 99 pages long. The middle book is 3 * 99 pages = 297 pages long.
So the answer is 297.

Question: April went to a concert that has two bands. 2/3 of the audience was there for the second band and 1/3 was there for the first band. 50% of the audience there for the second band is under the age of 30. Of this group, 60% are women and there are 20 men. How many people are at the concert?
Answer: Step-by-step reasoning process: Of the under - 30s there for the second band, 40% are men because 100 - 60 = 40. There are fifty under - 30s there for the second band because 20 / .4 = 50. There are 100 people there to see the second band because 50 / .5 = 100. There are 150 people at the concert because 100 / (2 / 3) = 150.
So the answer is 150.

Question: Jenna is hemming her prom dress. The dress's hem is 3 feet long. Each stitch Jenna makes is 1/4 inch long. If Jenna makes 24 stitches per minute, how many minutes does it take Jenna to hem her dress?
Answer:
Step-by-step reasoning process: First find how many inches the hem is by multiplying the length in feet by the number of inches per foot: 3 feet * 12 inches / foot = 36 inches. Then divide the length in inches by the length of each stitch to find how many stitches Jenna makes: 36 inches / .25 inches = 144 stitches. Then divide the number of stitches by Jenna's stitching rate to find how long it takes her: 144 stitches / 24 stitches / minute = 6 minutes.
So the answer is 6.
