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.
The number of pages that Xiao Ming had read after reading this extra-cursory reading material for a few days was one-ninth of the total number of pages. Then the number of pages he read every day was the total number of pages divided by one-ninth, which was the total number of pages/ 9. Then he read another 20 pages, so the total number of pages he had read was 20 + total pages/ 9, which was (20 + total pages) / 9. Combining the above two equations, we can get: Total pages = 9 * (20 + total pages/ 9) Transferring terms and reducing can be obtained: Total pages = 200 + 8 * total pages/ 9 Transferring the total number of pages/ 9 would yield: 8 * total pages/ 9 = 200 -total pages By solving the equation, one could obtain: Total pages = 1800 Therefore, this extra-cursory reading book had a total of 1800 pages. Xiao Ming had already read 200 + total pages/ 9 = 280 pages. There were 8 * total pages/ 9 = 160 pages left.
Xiao Ming was reading a storybook. The number of pages he read before dinner was one-fifth of the number of pages he had not read. After dinner, he read another six pages. At this time, the number of pages he had read was four of the number of pages he had not read…
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.
Wang Xiao was reading a novel. Before dinner, the number of pages he had read was one-seventh of the number of pages he had not read. After dinner, he read another eight pages. At this time, the number of pages he had read was the number of pages he had not read...
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 was reading a storybook. Before dinner, the number of pages he had read was one-fifth of the number he had not read. After dinner, he had read another six pages. This was the number of pages he had read was one-fifth of the number he had not read…
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.
Xiao Ming is reading a book. He had read 20% of the total number of pages on the first day. The number of pages read on the second day was 5:4 compared to the number of pages read on the first day. There were still 110 pages left to be read…
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.
Dongdong read a book on the first day, the ratio of the number of pages he had read to the number of pages he had not read was 2 to 3. The next day, he read another 30 pages, and the number of pages he had not read was this one
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.
Xiaofang read a story book. After a few days, the ratio of the number of pages read to the number of unread pages was 3:5. Later, she read another 27 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.
Xiao Ming is reading an extra-cursory book. This book has 150 pages. He has read three-fifths of the total pages. How many pages has he read and how many pages are left?
The total number of pages that Xiao Ming had read was 150. He had already read three-fifths of the total number of pages, which was 3/5 = 6%. Therefore, Xiao Ming had already read about 6% of the pages, and the remaining pages were 150 - 6%= 144 pages.
Xiao Lan was reading a storybook. 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 another 6 pages, which was 1/4 of the number of pages she had read.
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 + 6n= 36 + 6n= 42 Therefore, Xiaolan had read page 42 before dinner, but she hadn't read page 42-36=6.
Dongdong was reading a book with a total of 150 pages. At the end of the second week, he found that the number of pages he had not read was exactly the same as the number of pages he had read in the first week.
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.
Xiaofang was reading a storybook. Before dinner, the number of pages she had read was 1/7 of the unread pages. After dinner, she read another 8 pages. At this time, the number of pages she had read was 1/7 of the unread pages...
Xiaofang was reading a storybook. The number of pages she had read before dinner was 1/7 of the unread pages. After dinner, she read another 8 pages. At this time, the number of pages she had read was 1/7 + 8 = 19/7. Therefore, Xiaofang read 1/7 pages before dinner and 19/7 pages after dinner. 19 + 1/7 + 1/7 = 46/7 pages. Answer: Xiaofang read 1/7 pages before dinner, 19/7 pages after dinner, 46/7 pages in total.
