Q: Xiao Ming read an extra-cursory reading material. After reading it for a few days, the number of pages he had read was one-ninth of the total number of pages. Later, he read another 20 pages.

Xiao Ming read a storybook. The number of pages he read before dinner was one-fifth of the number of pages he did not read. After dinner, he read another six pages. At this time, the number of pages he read was four of the number of pages he did not read. According to the story, Xiao Ming had already read a part of the storybook before dinner, which was one-fifth of the unread pages. Therefore, the number of pages he read before dinner was one-fifth of the total number of unread pages. After dinner, he read another 6 pages. The number of pages he had read was one-fourth of the total number of pages he had not read, which was one-fourth of the total number of pages he had not read. Therefore, Xiaoming had read 11/10 of the storybook before and after dinner, which was also 11/10 of the unread pages. This ratio could be expressed as: Number of pages not seen/number of pages seen = 11/10 The number of unread pages is the ratio of the total number of pages, the number of read pages is the number of unread pages.

According to the plot of the novel, Wang Xiao had read about 70% of the novel before dinner, so he had read about 72% of the novel by the time he read eight pages after dinner. Since the ratio of the number of pages seen and the number of pages not seen was the same, Wang Xiao's number of pages not seen would increase by 8 pages, which was 16% of the content. Therefore, the ratio of the number of pages Wang Xiao had read before dinner to the number of pages he had not read was 1/7. After dinner, it was 167, which was about 2667%.

Xiao Ming read a storybook. The number of pages he had read before dinner was 1/5 of the number he had not read. After dinner, he read another 6 pages. This was the number of pages he had read, which was 1/4 of the number he had not read.

The total number of pages in the book was $30+30=60$pages. The number of pages read is $2x$, and the number of unread pages is $3x$. where $x$is an integral number. On the first day, the ratio of pages read to unread was $2:3, so $2x=3x+30. The solution is $x=10$. Therefore, the number of pages read is $2x=20$, and the number of unread pages is $3x=30$. So this novel has a total of $60$pages, I've read $20$pages, I haven't read $30$pages.

Xiao Ming reads a book on the first day, 20% of the total number of pages, and the number of pages read on the second day is 5/4 of the number of pages read on the first day, leaving 110 pages Assuming that the total number of pages in this book is x: I read 20% on the first day, which is 02x pages. I read 5/4x pages the next day because I read more pages the next day than the first day The remaining pages are x -02x- 5/4x = 110 pages Solve the equation: x = 1100 Therefore, the total number of pages in this book is 1100. Xiaoming read 200 pages on the first day and 300 pages on the second day.

Li Hua read a 500-page extra-cursory book. On the first day, he read 15% of the total number of pages. On the second day, he read 10% of the total number of pages. 1 5 On the third day, he read 20% of the total number of pages.

Xiaofang read a story book for a few days, and the ratio of the number of pages read to the number of unread pages is 3:5. Then, she read 27 pages. You can set the number of pages read as x the number of unread pages as 5x/3, so there is: x + 27 = 5x/3 The solution is x = 18 Therefore, Xiaofang had already read 18 pages, and there were 5 × 18/3 = 30 pages. She then read another 27 pages, so she had read 18 + 27 = 45 pages and still had 30 unread pages.

Xiaolan read a story book. The number of pages she had read before dinner was 1/5 of the number of pages she had not read. After dinner, she had read 6 pages. This was 1/4 of the number of pages she had read. Then, what was the number of pages she had not read? The number of unread pages is the number of pages in the entire story minus the number of read pages. Therefore, the number of pages that Xiaolan had read before dinner was 1/5 of the number of pages that she had not read. Number of pages seen = number of pages not seen × 5/4 He also knew that Xiaolan had read six pages after dinner, so he said," Number of pages seen = Number of pages seen + 6 = (Number of pages not seen × 5/4) + 6 (Add 6 to both sides of the equation) The equation was simplified to: Number of pages viewed = 26 × 5/4 + 6 = 36 + 6 = 42 Therefore, Xiaolan had read page 42 before dinner, but she hadn't read page 42-36=6.

(1)How many pages does Xiao Ming read every day? Since the number of days Xiaoming and Xiaomin read is different, but the total number of pages they read is the same, we can assume that Xiaoming reads x pages of extra-cursory books every day: 3x = 69 Solution:x = 23 Therefore, Xiao Ming read 23 pages of extra-cursory books every day. (2)How many pages of books does Xiaomin read every day? Since the total number of pages Xiaomin reads is 100 and the number of days she reads is 5, we can assume that she reads y pages of extra-cursory books every day: 5y = 100 Solution:y = 1667 Therefore, Little Min read 1667 pages of extra-cursory books every day.

Dongdong read a total of x pages at the end of the first week. The total number of pages in this book is 150, so: At the end of the second week, Dongdong had read (150 - x) pages. Dongdong hadn't finished reading 150 pages by the end of the second week, so he had read (150 - x) pages less than or equal to 150 pages. And because Dongdong had read page X in the first week: x = 150 - x + 1 = 149 The solution was x = 1, so Dongdong read a total of 149 pages in the first week. Dongdong had read (150 - 1) = 149 pages by the end of the second week. Therefore, Dongdong read a total of 149 pages in this book, and there was still one page left at the end of the second week.
