After 5 days, there were still 72 pages left, so he had read a total of $5+72=127$. This book has 132 pages, so Xiaoming reads an average of $132/127=10/9$pages per day. If he could only borrow it for 9 days, from the 6th day onwards, Xiaoming would have to deduct $6-5=1$page from the number of pages borrowed, so he still needed to read $132-1=131$page.

How many pages does Xiaofang read on average every day? You can use the following information to calculate how many pages she read before the sixth day: From the sixth day onwards, Xiaofang needed to return the book, so she needed to read 132 - 72 = 60 pages every day. Xiaofang read (60 x 6) / 7 = 48 pages before the sixth day. Therefore, Xiaofang read (48 + 60) / 2 = 32 pages on average every day. Answer: Xiaofang reads an average of 32 pages a day.

A book has a total of 90 pages. After reading it for two days, Little Light still has 30 pages left. 30 pages/2 days = 15 pages/day Because Little Light reads 15 pages of this book every day, the proportion of pages that Little Light reads every day is: 15/90 = 1/6 Therefore, Little Light read one-sixth of the book every day.

Xiaofang had been reading for 5 days and there were 36 pages left, so she had read a total of $5/36 = 180$pages. Xiaofang still needed to read $86 - 180 =-104$pages every day. Because the number of pages was negative, Xiaofang read an average of $${-104}$pages per day.

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.

After reading a book for 7 days, Xiao Ming still had 1/3 of the book left. This meant that he had read 1/3 of the book and the remaining 2/3 of the book needed to read 2/3 × 7 = 4/3 days. Reading a total of 60 pages in the next 5 days meant that Xiaoming had read (60/5) = 12 pages in these 5 days. Therefore, Xiaoming read an average of 12 pages a day.

Xiao Ming read a story book and read a total of 38 pages in the first two days and 54 pages in the next three days. We can use the total number of pages to deduct the number of pages in the first two days and the next three days to get the average number of pages that Xiaoming reads every day. Total pages = 38 + 54 = 82 In the previous two days, he had read 38 pages, so the ratio of the number of pages read in the previous two days to the total number of pages was 38 pages/ 82 pages = 047875, which could be approximately expressed as 047875. In the next three days, a total of 54 pages were read. The ratio of the number of pages read in the next three days to the total number of pages was 54 pages/ 82 pages = 06667, which could be approximately expressed as 06667. Therefore, on average, Xiaoming reads 047875 × 2 + 06667 × 3 = 016533 × 2 + 023333 × 3 = 039167 × 2 + 050938 × 3 = 089715 × 2 + 010785 × 3 = 1575 × 2 + 0192 × 3 = 27533 every day, which is about 275. Therefore, Xiao Ming read an average of 275 pages a day.

If Xiaoming reads 72 pages in the first 4 days, then Xiaoming's total page count in the first 4 days is 72 pages. Reading 29 pages every day for the next 6 days would mean that the total number of pages for the next 6 days would be 29 pages x 6 days = 171 pages. Therefore, Little Ming's total page count in the last six days was 171 pages. Little Ming read 171 pages per day for the next 6 days, 6 days = 27 pages. Therefore, Xiao Ming read an average of 27 pages a day.

Little Red read 24 pages a day for 5 days, so how many pages did she read in total: 5 days x 24 pages/day = 120 pages The rest of the book takes up 40% of the whole book, so the remaining pages take up: 40% ÷ 100% = 04 The pages of the book were: 120 pages/04 = 300 pages So this book has 300 pages.

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。
