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。

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.

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.
