A storybook, read an average of 15 pages a day. After reading for 12 days, the remaining pages are more than 2/7. How many pages are left?

Assuming that the storybook has x pages, then the number of pages read is x(15+12), and the remaining pages are x-(x(15 + 12)) = x-x(15 + 12) = x-3x (15 + 12) = -2x (15 +12) =-240. Therefore, there were still-240 pages left in the storybook.

If a book has 252 pages and has been read for 8 days and there are 12 pages left, then the total number of pages in the book is 252 - 12 = 240 pages. The number of pages he read every day should be 240/8 = 30 pages. Therefore, you should read 30 pages a day.

小敏读了3天还剩下234页那么她第一天读了 $\frac{234}{3}$ 页第二天读了 $\frac{234}{3} - \frac{1}{2}$ 页第三天读了 $\frac{234}{3} - \frac{1}{2} - \frac{1}{3}$ 页。 将这些式子代入到 $360 - 234 = 126$ 页中得到小敏平均每天读了 $126 \div 3 = 4333$ 页。 因为读书的时间需要连续所以小敏不能每天都读同一本书所以实际每天读的页数会稍微少一些。

Little Qiao read 18 pages of a storybook every day, and in a week, she read more than 20 pages of half of the book. The calculation method is as follows: In the first week, Little Qiao read 18 × 7 = 126 pages. The remaining pages were: The remaining pages of the book-the number of pages read in a week = the remaining pages- 126 - 126 = 100 pages. Thus, Little Qiao still had 100 pages to read.

Let's say this storybook has a total of $x$pages. According to the topic, 30 pages per day meant $30/div2 = 15$per hour. Zhang Ming read $15$pages per hour in $3$days so he read $3/30 = 90$pages in total. The remaining pages are $8/5 of the book, so there are: $$ 90 - \frac{8}{5} = \frac{16}{5} $$ Because the question requires the number of pages in the book, you need to multiply this result by $x$pages to get: $$ x \times \frac{16}{5} = \frac{16}{5} \times x = 96 $$ Solve this equation to get $x = 56$. So this story book had a total of $56$pages.

The average number of pages per day could be obtained by calculating the total number of pages per day and the remaining pages. Little Min had read the 120-page storybook for five days and was left with 35 pages. Therefore, the number of pages Little Min read every day was: 35 pages/5 days = 7 pages/day Therefore, Little Min read an average of seven pages a day.

This story book had a total of $90+170=260$pages.

Assuming the book has $x$pages: - $40$on the first day. - The next day, he read $40/times 2 = 80$pages. - On the third day, if you read $3/8$on $40$pages, you would read $10$pages. Because there was still $5/8 left, there was: $$ 40 + 80 + 10 = \boxed{120} $$ So this book has 120 pages.

According to the question, Cockroach read 5 days *20 pages/day =100 pages, and the remaining 15 pages of the book are equal to the total number of pages-100 pages that have been read, so the total number of pages is: 100 pages +15 pages =115 pages. The answer was page 115.
