The date when the book needs to be returned. If you look at page x every day: Borrowing time = 232 pages/x pages/day Return date = borrowing time + 1 day Since you can only borrow the book for 8 days, you need to return the book 1 day earlier, which is the end of the 7-day return date. He also needed to know the number of pages he had read in five days: 232 pages/5 days = 46 pages/day Therefore, the number of pages he read every day was: 46 pages/day = 23 pages/day Therefore, the number of pages he had read in the past five days was: 23 pages/day x 5 days = 115 pages The average number of pages he read every day was: 115 pages/5 days = 23 pages/day Answer:(1) I read an average of 23 pages a day. (2)He clearly had to return 160 pages on the sixth day (46 pages/day x 6 days), and the return date was the end of the fourth day.

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.

(1)There were still 80 pages left. (2)The remaining pages had to be read within four days, an average of 80 pages per day. This was equivalent to 80/170 = 05 days per page. Therefore, in the remaining 80 pages, you need to look at 80/05 = 16 days, 80/05 = 16 days, 80/05 = 16 days, and 80/05 = 24 days (rounded to two decimals). The final answer was that it took him 16 + 24 = 40 days to read the remaining 80 pages on the 16th and 24th days.

Xiao Ming reads a book with a total of 132 pages. After reading for 5 days, there are still 72 pages left. The total number of pages that Xiao Ming reads is 132 - 72 = 60 pages. If he could only borrow it for 9 days, then the total number of pages Little Ming needed to borrow was 60 pages/9 days = 6 pages/day. From the sixth day onwards, he read an average of 6 pages per day x 9 days = 54 pages. Answer 2: Assuming that from the first day onwards, Xiaoming reads x pages every day, then after he reads the number of pages borrowed in the previous 9 days, Xiaoming still needs to borrow 132 pages- 9 days x x pages = 132 pages- 9x pages. Therefore, we can write the equation: 132 pages- 9x pages = 1 page Solve this equation: 8x pages = 132 pages-9x pages = 23 pages x pages = 3 pages Therefore, Xiao Ming needed to read 3 pages/day, which was 9 pages, on the 6th day.

If a book has 170 pages and you read 12 pages a day, you can finish the book in 13 days. The calculation process was as follows: 13 days * 12 pages/day = 144 pages 170 pages plus 144 pages, 214 pages in total. Therefore, if you read 12 pages a day for 13 days, you would still have 214 pages left.

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。

Xiao Ming read a book for the first 4 days and read 15 pages, then read 6 pages every day for 5 days. We can use the following formula to calculate the average number of pages seen per day: Average number of pages read per day = total number of pages/days Substituting the total number of pages and the number of days into the formula, we get: Average number of pages read per day = 15 pages/4 days = 3 pages/day Therefore, Xiao Ming read an average of three 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.

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.
