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.
Ming Peng had been reading a 520-page storybook for seven days. There were still 170 pages left. How many pages did he read on average every day?
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 a storybook for 16 pages a day, but after reading it for five days, he had left 60% untouched. How many pages was this storybook?
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.
For a 120-page storybook, Little Min had 35 pages left after reading it for 5 days. 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.
A storybook has 252 pages. After reading it for 8 days, there are 12 pages left. How many pages do you read every day?
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 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?
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。
A fairy tale book had a total of 86 pages. Xiaofang had been reading it for five days, and there were still 36 pages left. How many pages does Xiaofang read on average 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 $${-104}$pages per day.
Zhang Ming was reading a storybook. He read 30 pages a day. After three days, there were still 8 pages of the book left. How many pages were there in this storybook?
Let's say this storybook has a total of $x$pages. According to the topic, 30 pages per day meant $30/div2 = 15$per hour. Zhang Ming read $15$pages per hour in $3$days so he read $3/30 = 90$pages in total. The remaining pages are $8/5 of the book, so there are: $$ 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 $$ Solve this equation to get $x = 56$. So this story book had a total of $56$pages.
Xiao Ming read a 480-page storybook and read page A every day for 12 days. How many pages are left?
When Xiao Ming read page A of the storybook every day for 12 days, he had read a total of 12 × page A. Therefore, when Xiaoming reads a 480-page storybook, he still has 480 - 12 × a pages left. To calculate the remaining pages, he needed to know how many pages Xiao Ming read in the end and how many pages he read every day. If we assume that the last page that Xiao Ming read was 480 pages and he reads page a every day, then we can write the following equation: 480 - 12 × a = Remaining pages By solving this equation, we can get: Remaining pages = 480 - 12 × a = 480 - 12a Therefore, after reading page A for 12 days, Xiao Ming still had 480 - 12A pages left.
A storybook, read an average of 15 pages a day. After reading for 12 days, the remaining pages are more than 2/7. How many pages are left?
There was a total of $12/15 - 1/15 = 165$pages left in the storybook. After reading the remaining two-sevenths, the remaining pages were two-sevenths of the original number. Therefore, he still needed to look at $165/div2/7 = 105$. Therefore, there were still 60 pages left.
Reading a storybook every day, 40 pages a day. After 3 days, there is still 5/8 of the Golden Book left. How many pages is this book?
Assuming the book has $x$pages: - $40$on the first day. - The next day, he read $40/times 2 = 80$pages. - On the third day, if you read $3/8$on $40$pages, you would read $10$pages. Because there was still $5/8 left, there was: $$ 40 + 80 + 10 = \boxed{120} $$ So this book has 120 pages.
