Reddie had read a 140-page storybook, and there were still three-sevenths of the total number of pages left. How many pages had Reddie read?

Let's say this storybook has a total of $x$pages. Naughty had finished reading $5/7$of the total page count, which meant that he had $2/7$left. Therefore, Naughty still needed to read $40$to finish the total number of pages. According to the meaning of the question, mischievous still needs to look at $40$pages, so $x - 40$should be divided by $7$. Since $x$is the total number of pages,$x$should be greater than or equal to $40$. Therefore, we can write an equation: $$x \geq 40 + 40 \times 7 = 560$$ The solution to this equation is $x=567$. So this story book had a total of $567$pages.

The number of pages in a storybook can be expressed as $x$, so the total number of pages is $x \times 3/5$. Since there were still 36 pages to read, the total number of pages in the storybook plus these 36 pages was $x/times 3/5 + 36$. And because the book had a total of $x$pages, the equation could be listed: $$x \times 3/5 + 36 = x$$ If you solve this equation, you get $x=300$. Therefore, the story book had a total of $300$pages.

When Xiao Jin read a 72-page storybook, the number of pages he had read was two-sevenths of the number of pages he had not read. Number of pages seen = number of pages not seen div7 = 1267 Therefore, Xiao Jun had already read a lot of pages, about 1267 pages.

Let's assume that the total number of pages in this book is x. Naughty had already read 5/7 of the total number of pages, which meant that he had already read 3/5 of x pages. Therefore, he still had 2/5 of x pages to read. There are still 40 pages to read, so the total number of pages that Naughty still needs to read is: 2/5 of x + 40 To simplify it: x + 40 / 5 The general score was: x + 80 Since x is the total number of pages: x + 80 = x / 5 + 80 To simplify it: x = 400 Therefore, the book had a total of 400 pages.

The storybook has a total of 100 pages. The number of pages that have been read is four times that of the number of pages that have not been read. The known number of pages seen = the number of pages seen + the number of pages left, which was 4 unseen pages = the number of pages seen + the number of pages left. Transferring the items would yield 5 pages remaining = 4 pages viewed, which meant that the remaining pages = 4 pages viewed divided by 5. Since the story book has a total of 100 pages, 4 pages viewed/5 = 8 pages remaining. Thus, there were still eight pages left.

Assuming that this storybook has a total of $x$pages: - The number of pages Zhang Ming read every day was $30. - The number of pages required to read the book in 3 days was $30,000. - The remaining page count was $58. Therefore, we can write an equation to solve this problem: $$ 30x + 58 = x $$ By solving this equation, one could obtain: $$ x = 58 - 30 = 28 $$ Therefore, this storybook had a total of 28 pages.

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.

When Xiao Ming read page A of the storybook every day for 12 days, he had read a total of 12 × page A. Therefore, when Xiaoming reads a 480-page storybook, he still has 480 - 12 × a pages left. To calculate the remaining pages, he needed to know how many pages Xiao Ming read in the end and how many pages he read every day. If we assume that the last page that Xiao Ming read was 480 pages and he reads page a every day, then we can write the following equation: 480 - 12 × a = Remaining pages By solving this equation, we can get: Remaining pages = 480 - 12 × a = 480 - 12a Therefore, after reading page A for 12 days, Xiao Ming still had 480 - 12A pages left.

Li Mingpan had read 1/3 of the total page on the first day and 2/5 of the total page on the second day. Total page count-1/3 of the total page count on the first day-2/5 of the total page count on the second day = total page count-1/3 of the total page count on the first day- 2/3 × total page count = 2/3 × total page count Therefore, the book still had 2/3 x total pages = 4/9 pages left.
