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.

On the first day, Xiaofang read the book's 51 pages, and the remaining pages were $51/div2 = 25$. The next day, he read another 10 pages and the remaining pages were $25 + 10 =$35. At this point, the ratio of pages seen to pages not seen is 2:3, which can be expressed as $25:35=2:3$. Therefore, Xiaofang had read the book for $2+3=5$days and still had $35-5=28$pages left.

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.

Xiaofang read 15 of the book on the first day and read 10 pages on the second day, so she read a total of ${1}{5} +{1 = 15}$pages. Assuming that the book has a total of $x$pages, then Xiaofang has read a total of $x \times \frac{1}{5} + x \times \frac{10}{1 = 10x + 50}$pages. At this time, the ratio of the number of pages read to the number of pages not read is 2, which means that the number of pages left by Xiaofang is twice the number of pages in the book, which is $x/times 2 = 10x + 50$. The solution is $x = 105$, which means that the book has 105 pages. Xiaofang read 15 pages on the first day and 10 pages on the second day. She read 25 pages in total.

According to the ratio of the number of pages read to the number of pages unread on the first day was 2:7, the number of pages unread was 2/7 of the number of pages read. Because he read 42 pages the next day, the number of pages read was 42/2/7=91(pages), and the number of unread pages was 42/(2/7)=63(pages).

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.
