The information you provided is not detailed enough to determine the total number of pages in this book. Please provide more information so that I can answer your questions.

Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?

The total number of pages in this book is x. On the first day, I read three-fifths of the total number of pages, which is 3/5x pages on the first day. Reading 20% the next day meant reading 20% x 3/5 x = 2/5 x pages. Because he read 2/5x pages the next day, the remaining pages were 1 - 2/5x = 3/5x pages. Because Kobayashi read 3/5x pages, the total number of pages Kobayashi read was 3/5x + 2/5x = 5/5x pages. And because there were still 20 pages left in Kobayashi's book, 20 = 3/5x + 2/5x solved the equation to get x = 120. So this book has 120 pages.

Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?

Let the total number of pages in this book be x pages: - I read 3/5x pages on the first day. -20% read the next day =02x pages. According to the meaning of the question, the remaining pages were x-(3/5x+02x)=20 pages. Substituting x=50 pages gives: - I read 3/5 x 50 pages =30 pages on the first day. - The next day, I read 02 x 50 pages =10 pages. Therefore, the book had a total of 50 pages.

Xiao Ming read a story book. On the first day, he read 30 pages, which was three-fifths of the total number of pages in the book. On the second day, he read one-tenth of the whole book.

小明看一本故事书第一天看了30页是全书总页数的五分之三那么第一天看了全书的 $\frac{30}{5}$ 页. 第二天看了全书的十分之一即第二天看了 $\frac{1}{10}$ 页. 因此第二天看了 $\frac{30}{5} \cdot \frac{1}{10} = \frac{3}{5}$ 页. 所以小明在第二天看了 $\frac{3}{5}$ 页也就是全书的 $\frac{3}{5}$ 页.

Three fifths of a book has been read, and there are 15 pages left. The number of pages read is a fraction of the number of pages not read

If a book has been read three-fifths of the way and there are 15 pages left, then the number of pages read is the number of pages not read: Number of pages seen/number of pages not seen = 3/5/4/5 = 3/4 Therefore, the number of pages that had been read was four-thirds of the number of pages that had not been read.

Xiao Ming is reading a book. He had read 20% of the total number of pages on the first day. The number of pages read on the second day was 5:4 compared to the number of pages read on the first day. There were still 110 pages left to be read…

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.

Xiaoming reads a book on the first day, reading 20% of the total number of pages, the number of pages read on the second day and the number of pages read on the first day is 5:4

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.

A 180-page book, read two-fifths of the total, the next day read one-third of the total, how many pages are left

If a book had 180 pages and two-fifths of the total number had been read, then there would be 180 × 2/5 = 72 pages left. The next day, he read one-third of the total, so he had 180 × 3/10 = 24 pages left. Therefore, there were 72 + 24 = 106 pages left in the book.

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.
