Teacher An has been reading for four days and there are 252 pages left. So how many pages does he need to read on average every day? We can use the formula of "page count/day count" to calculate. 580 pages/4 days = 145 pages/day Therefore, Teacher An had to read an average of 145 pages a 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.
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。
Ming Peng had been reading for seven days and had 170 pages left. Therefore, the average number of pages he read every day was: 170 pages/7 days = 24 pages/day Therefore, he read an average of 24 pages a day.
He had been reading for five days and there were still 90 pages left, so he still needed to read 350 - 90 = 260 pages every day. Therefore, he read an average of 260 pages/5 = 52 pages a day.
As a person who loves reading novels, I can't provide actual information about books. However, according to the common plot of a novel, the content that should be read on the fourth day should usually be the climax or the end of the story so that the reader has an overall reading experience. Therefore, it was suggested that one could choose one or more of the passages from the plot and structure of the novel as the reading content for the fourth day.
Lili spent 8 days to finish reading a storybook. She read 150 pages in the first 3 days and 42 pages a day in the next 5 days. So she read a total of $150/times 3 + 42/times 5 = 2220$pages. And the total time she spent was $8$days, so she read an average of $2220 / 8 = 265$pages per day. So Lili read an average of 265 pages a day.
The remaining 5 days need to read 180 pages/5 = 36 pages/day Therefore, Xiaoxiao needed to read 36 pages on average every day.
For the remaining five days, he would need to read 180 pages- 80 pages = 100 pages every day. Therefore, he read an average of 100 pages a day.
Uncle Wang planned to finish reading a 217-page novel in 15 days. He read a total of 112 pages in the first 8 days. How many pages does he read on average every day? Uncle Wang had read 112 pages in the first 8 days, so the total number of pages he needed to read in the remaining 15 days was: 15 days x 112 pages/day = 1656 pages Since he planned to finish the book in 15 days, the total number of pages he needed to read had to be a whole number. Therefore, he needed to divide 1656 pages by 15 days to get: 1656 pages/15 days = 104 pages/day For the remaining 15 days, Uncle Wang needed to read 104 pages a 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.
