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.

Xiao Ming read 20% of the total number of pages on the first day of reading a book, which means that the total number of pages multiplied by 20% equals 20% of the total number of pages. On the second day, the ratio of pages read on the first day was 5:4, which meant that half of the total pages read on the second day was 25% of the total pages. Therefore, Xiao Ming read the total number of pages multiplied by 25% the next day, which was equal to the total number of pages multiplied by 5%. Divide the total number of pages by 5 to get the number of pages that Xiaoming read the next day divided by 5. That is, the total number of pages divided by 5 multiplied by 40% equals the total number of pages multiplied by 10%. Therefore, Xiao Ming read the total number of pages multiplied by 10% the next day, which was equal to the total number of pages multiplied by 5.

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.

Wang Hong read a book on the first day, read 3/7 of the total pages, and the next day, read 1/4 of the total pages. How much of the book was left? Answer: The total number of pages in the remaining books is 3/7 of the total number of pages plus 1/4, which means the total number of pages is 8/7 plus 1/4, which is 9/11. Therefore, Wang Hong still had 9/11 of the book to read.

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.

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.

Xiao Ming read 3/8 of the book on the first day, which was 042675 or 42675% of the book. The next day, he read 18 pages, and the remaining pages were 5/8 of the book, which was 075 or 75%. Suppose the book has x pages: 3/5 of the total number of pages read = (x * 3/8 + 18) / x = 3/5 To simplify it: x = 42 * 8 / 3 = 96 Therefore, the book had a total of 96 pages.

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. If the total number of pages in this novel is X, then the number of pages that Little Red reads on the first day is X/12+19, the number of pages that she reads on the second day is X/8-17, and the remaining number of pages is X-93. According to the meaning of the question, the following equation can be listed: The number of pages Xiaohong read on the first day + the number of pages Xiaohong read on the second day = X/12+19+X/8-17 = X To simplify it: X = 962 Therefore, the total number of pages in this novel was 962. On the first day, Little Red read 962/12+19=86 pages. On the second day, she read 962/8-17=105 pages. The remaining pages were 962-93=871 pages. Little Red had read a total of 962+871=1733 pages, which was 93 pages less than the actual total number of pages. Therefore, Little Red had actually read 1733-93=1640 pages.

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.

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.
