Xiao Jin is reading a 72-page storybook. The number of pages he has read is two-sevenths of the number of pages he has not read. How many pages has Xiao Jun read?
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.
When someone reads a 252-page novel, the number of pages he has read is equivalent to 2 and 1/2 times the number of pages he has not read. How many pages has he read?
Let the number of pages he has read be x and the number of pages he has not read be 252-x. According to the meaning of the question, the equation could be listed: x × 5/7 = (252 - x) × 2 × 1/2 To simplify it: 5x = 1260 - 7x 8x = 1260 x = 150 Therefore, he had already read 150 pages, and the number of pages he had not read was 252-150=102 pages. Therefore, he had read page 150 but not page 102.

A book has 170 pages. How many pages has Xiao Jun not read yet?
There are 170 pages in a book. You can get the answer by calculating the length of each page. The length of each page usually refers to the length of each page. The number of pages may vary according to different publishing houses and different format. Usually, the length of each page is 255mm or 305mm, but some books use different size. Therefore, for a 170-page book, each page is 255 millimeters long, so the number of pages in the book is: 170 pages/255mm/page = 692 pages Therefore, Xiao Jun still had about six pages to read.
Xiao Ming was reading a storybook. The number of pages he read before dinner was one-fifth of the number of pages he had not read. After dinner, he read another six pages. At this time, the number of pages he had read was four of the number of pages he had not read…
Xiao Ming read a storybook. The number of pages he read before dinner was one-fifth of the number of pages he did not read. After dinner, he read another six pages. At this time, the number of pages he read was four of the number of pages he did not read. According to the story, Xiao Ming had already read a part of the storybook before dinner, which was one-fifth of the unread pages. Therefore, the number of pages he read before dinner was one-fifth of the total number of unread pages. After dinner, he read another 6 pages. The number of pages he had read was one-fourth of the total number of pages he had not read, which was one-fourth of the total number of pages he had not read. Therefore, Xiaoming had read 11/10 of the storybook before and after dinner, which was also 11/10 of the unread pages. This ratio could be expressed as: Number of pages not seen/number of pages seen = 11/10 The number of unread pages is the ratio of the total number of pages, the number of read pages is the number of unread pages.
Xiao Ming is reading an extra-cursory book. This book has 150 pages. He has read three-fifths of the total pages. How many pages has he read and how many pages are left?
The total number of pages that Xiao Ming had read was 150. He had already read three-fifths of the total number of pages, which was 3/5 = 6%. Therefore, Xiao Ming had already read about 6% of the pages, and the remaining pages were 150 - 6%= 144 pages.
Xiao Ming is reading a 150-page storybook. He has already read two-fifths of the book. How many pages are left?
Xiao Ming had already read two-fifths of a 150-page storybook, so he had already read 150 × 2/5 = 60 pages. Therefore, there were still 150 - 60 = 90 pages left in the storybook.
Dongdong reads a book on the first day. The ratio of the number of pages he has read to the number of pages he has not read is two to three. The next day, he reads 30. At this time, the number of pages he has not read is this
Suppose the book has a total of $n$pages, the number of pages read is $m$, and the number of unread pages is $n-m$. According to the question, the ratio of the number of pages read to the number of pages unread is two to three, and the following equations can be listed: $$ \begin{cases} m = 2(n-m) \\ m + 30 = n \end{cases} $$ Transforming the second equation into $n = 4m + 30$and replacing it into the first equation gives $2m = 30$. The solution is $m = 15$. So the book has a total of $n=50$pages, the number of pages read is $m=20$, and the number of unread pages is $n-m=30$.
A storybook has a total of 100 pages. The number of pages that have been read is four times the number of pages that have not been read. How many pages have been read? How many pages are left?
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.
A storybook had 56 pages, and Xiaofang had read seven times the number of pages left. How many pages has Xiaofang read?
The total number of pages that Xiaofang had read was 56. The remaining pages were 56-1=55 pages. The number of pages that Xiaofang had read was 55×7=355 pages.
Naughty is reading a storybook. He has read 5/7 of the total number of pages. There are still 40 pages left. How many pages does this book have? Trouble calculating!
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.
