There were 360 pages in a storybook. After reading for 3 days, Little Min had 234 pages left. How many pages did she read on average every day?

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.

He had read 16 pages of a storybook every day for five days, leaving 60% untouched. We can use the formula "book page number = total page number x page percentage" to solve this problem. The total page number is the number of pages that have been read plus the number of pages that have not been read, and the page percentage is the proportion of the number of pages that have not been read to the total number of pages. According to the question, he had read 16 × 5 = 80 pages in five days. The remaining number of pages was 60%, 36 pages. Therefore, the total number of pages in this storybook was 80 + 36 = 116 pages.

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.

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.

There was a total of $12/15 - 1/15 = 165$pages left in the storybook. After reading the remaining two-sevenths, the remaining pages were two-sevenths of the original number. Therefore, he still needed to look at $165/div2/7 = 105$. Therefore, there were still 60 pages left.

Let's say this storybook has a total of $x$pages. Reading $60$pages a day, the number of pages Little Light read in $3$days was: $$60\times3=180$$ The remaining pages are 5/8 of the book, so the following equation can be written: $$x\div5=8\times60\times3$$ Solve this equation: $$x=2400$$ So this storybook had a total of $2400 pages.

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.

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.

Little Min had already read 30 pages and there were still 50 pages left.
