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.
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.
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.

A book had a total of 95 pages. Xiao Hong read 13 pages a day. Could she finish it in a week?

A book has a page, read 15 pages a day, and finish it in a week
A book has a page A. Reading 15 pages a day in a week is just enough. Assuming a book has page A and 15 pages a day, the number of days needed to finish the book in a week is: a ÷ 15 = (a + a) ÷ 2 = 2a / 2 + a / 2 Transferring items can be sorted out: 2a / 2 = a + a / 2 To simplify it: a = 4 Therefore, a book had four pages, and 15 pages a day was just enough to finish it in a week.
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.
Xiao Hong read a novel. On the first day, she read 9 pages more than 1/12 of the total number of pages. On the second day, she read 7 pages less than 1/8 of the total number of pages, leaving 93 pages.
The total number of pages Little Red read on the first day was (12+9)/(12×1+9)= 13 pages. The total number of pages Xiao Hong read the next day was (13-7)/(8×1+7)= 9 pages. The number of pages Little Red read the next day was 7 pages less than the first day, and the remaining pages were 9 pages more than the first day. Therefore, the total number of pages she read the next day was 9/7 times that of the first day, which meant that she read 18 pages the next day. According to the total number of pages read on the first day and the total number of pages read on the second day, the total number of pages of the novel could be calculated as:13+9+18=40 pages. Therefore, the novel that Little Red was reading was the 40-Page Fictions.

Xiao Hong read a novel on the first day, and she read 1/12 of the total number of pages, which was 19 pages more. On the second day, she read 17 pages less than 1/8 of the total number of pages, leaving 93 pages. On the first day, he read 1/12 of the total page count, which was 19 pages more. On the second day, he read (1-1/12)×19 = 11/12 pages. Since there were 93 pages left, he read 93/11/12 = 108 pages. The next day, if you read 17 pages less than 1/8 of the total number of pages, then you read (1-1/8)×17 = 7/8 pages the next day. Since there were 93 pages left, you read 93/7/8 = 160 pages the next day. Therefore, the total number of pages Little Red had read was 160+93=253.
