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.
How many pages are there in this storybook? Xiaofang had read 1/7 of page before dinner and 8 pages after dinner, so she had read 1/7 + 8 pages, which was 11/7 pages. Then this storybook had a total of (11/7) + 1 = 18/7 pages.
Xiaofang read the novel as follows: Before dinner, Xiaofang had read less than one-seventh of the novel, which was about 16 pages. Therefore, she had read less than one-seventh of the novel before dinner. After dinner, Xiaofang read another eight pages. At this time, she had read about 1/7 + 1/8 = 1/4 of the novel. Therefore, Xiaofang read another quarter of the novel after dinner. To sum up, Xiaofang had read 16 pages before dinner and 1/4 pages after dinner, a total of 3/4 pages.
Xiaofang was reading a novel. The number of pages she had read before dinner was one-seventh of the number that she had not read. After dinner, she read another eight pages. At this time, she had read 7/8 pages of the novel.
Xiaofang was reading a novel. The number of pages that she had read before dinner was one-seventh of the unread pages, which meant that she had read about 70% of the novel. After dinner, she read another eight pages, and now she had read about 140 pages, so it could be calculated that she had read about 20 pages before dinner. In that case, she had read about 90% of the novel before and after dinner.
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 read 15 of the book on the first day and read 10 pages on the second day, so she read a total of ${1}{5} +{1 = 15}$pages. Assuming that the book has a total of $x$pages, then Xiaofang has read a total of $x \times \frac{1}{5} + x \times \frac{10}{1 = 10x + 50}$pages. At this time, the ratio of the number of pages read to the number of pages not read is 2, which means that the number of pages left by Xiaofang is twice the number of pages in the book, which is $x/times 2 = 10x + 50$. The solution is $x = 105$, which means that the book has 105 pages. Xiaofang read 15 pages on the first day and 10 pages on the second day. She read 25 pages in total.
On the first day, Xiaofang read the book's 51 pages, and the remaining pages were $51/div2 = 25$. The next day, he read another 10 pages and the remaining pages were $25 + 10 =$35. At this point, the ratio of pages seen to pages not seen is 2:3, which can be expressed as $25:35=2:3$. Therefore, Xiaofang had read the book for $2+3=5$days and still had $35-5=28$pages left.
