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.
How does the ending of the first week of salt and shelter affect the second week
Salt and Sanctuary is a Japanese novel about a young girl and a mysterious creature and their journey. The effect of the first week's ending on the second week's ending depended on the plot and ending of the novel. If the first round ended with a conflict between the girl and the mysterious creature, the second round might have a different development because the girl needed to find a way to resolve the problem so that she could reconcile with the mysterious creature and continue their journey. On the other hand, if the first week ends with the girl reconciling with the mysterious creature, then the second week may have a different development because the girl may need to explore more mysterious creatures or she may choose to leave the area and look for new adventures. The effect of the ending of Salt and Sanctuary on the second week depended on the plot and ending of the novel, so it needed to be carefully considered.
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.

The bookstore sold 1600 books in the first quarter, three-fifths less than in the second quarter. How many books were sold in the second quarter? (I need an algorithm)
The bookstore sold 1600 books in the first quarter, three-fifths less than in the second quarter. How many books were sold in the second quarter? Assuming that the number of books sold in the second quarter is x: - The number of books sold in the first quarter was 1600; - The second quarter was less than three-fifths of the first quarter: The number of books sold in the second quarter = the number of books sold in the first quarter × 1 -three-fifths = 1600 × 1 - 3/5 = 1440 books; - Therefore, the number of books sold in the second quarter was 1440.
