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.
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.
Xiaofang read a storybook. On the first day, she read part of it. The ratio of the number of pages read to the number of pages unread was 2:7. On the second day, she read 42 pages.
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).

Xiaofang was reading a storybook. The number of pages she had read before dinner was 1/7 of the unread pages. After dinner, she read another 8 pages. At this time, the number of pages she had read was 1/7 + 8 = 19/7. Therefore, Xiaofang read 1/7 pages before dinner and 19/7 pages after dinner. 19 + 1/7 + 1/7 = 46/7 pages. Answer: Xiaofang read 1/7 pages before dinner, 19/7 pages after dinner, 46/7 pages in total.

Xiaofang read a storybook. The number of pages she had read before dinner was 1/7 of the number of pages she had not read. After dinner, she read another 8 pages. Assuming that the total number of pages in the storybook was 100. The number of pages read before dinner is 10 pages, the number of pages not read is 100 pages- 10 pages = 90 pages. After dinner, he read another 8 pages, so the number of pages he had read was 10 + 8 = 18. The ratio of the number of pages seen to the number of pages not seen was 18 pages/90 pages = 1/7. Therefore, Xiaofang had already read 7 pages before dinner, and the remaining pages were 93 pages. She read 8 pages after dinner, so she had read 93 pages + 8 pages = 101 pages in total.
Naughty was reading a storybook. He had already read 5/7 of the total number of pages. There were still 40 pages left. How many pages were there in this storybook?
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.
I read 90 pages of a storybook on Monday and the remaining 170 pages on Tuesday. How many pages are there in this storybook?

Huanhuan has already finished reading three-fifths of the total number of pages in the storybook. There are still 36 pages left. How many pages are there in this storybook?
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.
