Su Qian read a novel. In the first week, he read 20% of the total pages of the novel. In the second week, he read 30% of the remaining pages. At this time, there were 140 pages left.
According to the 20% of the total number of pages Su Qian read in the first week, the ratio of the total number of pages he read in the first week was: 20% ÷ 100% = 02 Therefore, Su Qian read 0.2 of the total number of pages in the first week, which was 20%. Next, based on the 30% of the remaining pages that Su Qian read in the second week, the ratio of the total number of pages that he read in the second week was calculated as: 30% ÷ 100% = 03 Therefore, Su Qian read 0.3 of the total number of pages in the second week, which was 30%. Then, the total number of pages left in the novel was: 140 + 02 = 880 Therefore, there were 880 pages left in the novel.

Xiao Hong read a book. In the first week, she read 30%. In the second week, she read 55 pages. At this time, the ratio of the number of pages read to the total number of pages was 2:3.
Xiao Hong read 30% in the first week and 55 pages in the second week. The ratio of the number of pages read to the total number of pages is 2:3. We can set the total number of pages of this book as x pages. According to the question, Xiao Hong had already read 30% of the first week, which was 03x pages. In the second week, she had read 55 pages, so she had already read 03x + 55 pages. The ratio of the number of pages seen to the total number of pages is 2:3, so there is: 03x + 55 = 2/3x Solve the equation: 13x + 55 = 2/3x 13x - 2/3x = 55 01x = 55 x = 550 Therefore, the total number of pages in this book was 550.
Yueyue read a book. In the first week, she read 1/4 of the book. In the second week, she read the remaining 1/5. There were 120 pages left.

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.
Little Light read 3/8 of the book in the first week, and the remaining 1/5 in the second week. There were 34 pages left. He did not look at how many pages the book had.
Let's say the book has $x$pages. Little Light read $3/8$pages of the book in the first week, so he read $3/8 times x$pages. The remaining pages are $x - 3/8 <em> times x = 5/8 <em> times x$pages. The next week, he read the remaining $1/5$pages, so he read $1/5 times 5/8 times x$pages. According to the question, Little Light had read a total of $3/8'times x + 1/5'times 5/8'times x = 17/40 'times x$pages. Since Little Light did not read the book, the remaining pages were $34$. Therefore,$x - 17/40 So the book had a total of $960$pages.
Naughty read a storybook. On the first day, he read 40% of the total pages. On the second day, he read 24 pages less than the first day. There were still 56 pages left. This book…
The total number of pages in this book is 100 pages. On the first day, I read 40 pages. On the second day, I read 24 pages less than the first day. Therefore, the number of pages I read on the second day is the number of pages I read on the first day plus 24 pages. The next day, he read 40 + 24 = 64 pages. So the total number of pages in the book was 100. Naughty read 40 pages on the first day and 64 pages on the second day. The remaining pages were 100 - 64 = 36 pages. On the first day, Naughty had read 40% of it, which was four pages. The next day, he read page 64/4 = 14. Therefore, the number of pages left for Naughty was 36 - 14 = 22. So, in the end, Naughty finished reading 22 pages, which was four pages less than the first day.
Xiao Gang read a book. On the first day, he read 30% of the total number of pages. On the second day, he read 4 pages less than the first day. There were 44 pages left. How many pages were there in this book?
Let's say the book has x pages. 30% read on the first day = 03x pages, the remaining pages are x-03x = 07x pages. The next day, I read 4 pages less than the first day, so I read 07x-4 pages the next day. According to the meaning of the question, the remaining pages are 44 pages, so there are: 07x-4 = 44 Solve the equation: 07x = 48 x = 64 So this book has 64 pages.
How many pages were there in the storybook? Xiaoming had read 28 pages on the first day, and on the second day, he had read 1/5 of the total number of pages. There was still 1/3 of the total number of pages left?

Xiaowen read a book. In the first week, she read a quarter of the book. In the second week, she read a fifth of the book. There were 165 pages left.
In the first week, Xiaowen had read a quarter of the book, which meant that she had read 1/4 of the book. In the second week, Xiaowen had read one-fifth of the book, which meant that she had read 1/5 of the book. The ratio of the remaining books was $1-1/4-1/5=16/20$. Because Xiaowen hadn't finished reading the entire book, she needed to look at the ratio of $16/20$, which was $8/20$. If the book has a total of $x$pages, then $x=16/20*165$. The solution is $x=2400$. So the book had a total of $2400 pages.
Wang Liang had read 96 pages of the novel, and then read the remaining 2/3. At this time, he had not finished reading 1/7 of the total pages. How many pages was this novel?
Let's say this novel has a total of $x$pages. Wang Liang had already read $96$, so the remaining pages were $x - 96$. The number of pages remaining is $2/3$, so the number of pages remaining is $x - 96/div2/3 = 48$. According to the meaning of the question, the number of pages that were not finished accounted for $1/7$of the total number of pages, so the number of pages that were not finished was $48/div1/7 = 64$. Therefore, this novel has a total of $x = 96 + 64 = 150$pages.
