Xiao Ming and Xiao Hong were reading a 24-page book at the same time. Xiao Hong finished reading the book in 3 days. How many pages did she read per day on average?
Little Red saw that the number of pages in this book was 24 pages/day x 3 days = 72 pages. The total number of pages she had read was 72, and there were no more pages left. Therefore, Xiao Ming and Xiao Hong read a 24-page book at the same time. Xiao Hong finished the book in three days, and she read an average of 72 pages a day.
A book had 372 pages. Xiao Hong finished reading it in six days, and Xiao Gang finished reading it in a week. How many pages did Xiao Gang read on average every day?
According to the information provided by the question, Little Red spent six days to finish reading 372 pages. The average number of pages she read per day was: 372/6 = 60 pages/day Therefore, Xiao Gang needed to multiply it by 15 days to get the average number of pages he read every day: 60 pages/day x 15 days = 90 pages/day Therefore, Xiao Gang read an average of 90 pages a day.
Xiao Hong read a book with 95 pages for five days. Xiao Li read this book with 30 pages a day. On average, how many pages did Xiao Hong read less than Xiao Li every day?
Xiao Hong spent a total of five days reading this book and had read a total of 95 pages. Xiaoli read 30 pages a day for a total of 5 days, so Xiaoli read a total of 30 × 5 = 150 pages. Then how many pages does Xiao Hong read less than Xiao Li on average every day? The total number of pages that Xiao Hong read was 95. The total number of pages that she read every day was 95/5 = 19. The total number of pages Xiao Li read was 30 x 5 = 150 pages. The total number of pages she read every day was 30 pages. This was because Xiao Hong read 19 - 30 = -1 pages less than Xiao Li every day. Therefore, Xiao Hong read an average of 19 pages less than Xiao Li every day.
Question: Xiao Hong borrowed a book. After reading it for five days, there were still 12 pages left. Xiao Hong had to return the book in three days. How many pages did she read on average every day?
Xiao Hong borrowed a book and read it for 5 days. There were still 12 pages left, so she had read a total of $5+12=17$pages. Little Red had to return the book in 3 days, so the number of pages she needed to return was $17+3=20$pages. We can calculate the average number of pages of the remaining pages per day using the following formula: $$ Remaining pages = total pages-number of pages already seen $$ Since Little Red had already read 17 pages, the remaining pages should be $17- 17> times 2=0$per day. Therefore, Little Red had to read an average of 0 pages a day.
How many days can Xiao Hong read a 211-page book for 30 minutes a day?
If Xiao Hong reads a 211-page book for 30 minutes a day, her reading speed will be faster. She can read 6 pages per minute. Therefore, Little Red could read 30 minutes or 180 pages a day. Since each book has nine pages, a 211-page book has a total of 211/9=23(pages)3(pages). Therefore, Little Red needed to read 23 pages to reach the last page of the book. Little Red needed to read for 30 minutes every day, so she could read 23 pages divided by 30= (pages) days. Therefore, Little Red needed seven days to finish reading this 211-page book.
Xiao Xiao was reading a 150-page book. She had read two-fifths of the book in four days. How many pages were left?
Xiao Xiao read a 150-page book for four days and read two-fifths of the book. Xiaoxiao reads 1/5/4 = 1/10 of the book every day The book had 150 pages, so Xiaoxiao still needed to read pages 1 - 1/5 - 1/10 = 4/5. And because Xiaoxiao had already read two-fifths of the book, there were still four to five pages left. Hence, Xiao Xiao still needed to read 2/5 pages.

Ya-chan reads a 114-page book, on average, 12 pages a day. After a few days, there are still 18 pages left.

In these nine days, Ya-chan needed to read 12 pages a day, so in total, he would read: 12 pages/day x 9 days = 108 pages However, there were still 18 pages left, so Ya-chan had to read the remaining 18 pages every day: 18 pages/day = 1 page In other words, Ya-chan needed to read an extra page of the remaining 18 pages every day to finish the book.
Xiao Hong was reading an extra-cursory book. She had been reading it for three days and had read an average of 38 pages a day. She had already read 108 pages. On the fourth day, which page should she start reading?

Xiao Dong read a 420-page book. He read 26 pages a day. After reading for 13 days, how many pages were left?
Xiao Dong read a 420-page book. He read 26 pages a day, and after 13 days, there were still pages left. The calculation process was as follows: The total number of pages he read in 13 days was 26 * 13 = 336 pages. The total number of pages in this book is 420, so the total number of pages needed to read the whole book is 420. Therefore, the number of pages Little Dong needed to finish reading the book in 13 days was 336 pages/13 days = 26 pages/day. Because Xiao Dong read 26 pages every day, the total number of pages he read every day was 26 + 26 = 52. Therefore, the number of pages Little Dong needed to finish reading the book in 13 days was 52 pages/13 days = 4 pages/day. Because Xiao Dong read four pages a day, the remaining pages were 420 - 4 * 13 = 420 - 52 = 368. Therefore, Xiao Dong still had 368 pages to read.
