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.
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.
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.
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.
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.
A storybook had 156 pages. Xiao Ming read it for three days and there were still 12 pages left. How many pages does Xiao Ming read on average every day? [Solution to the equation]
Suppose Xiaoming reads an average of x pages every day: The total number of pages read in 3 days is:3 × 156 = 458 pages Look at the remaining pages:12 pages Therefore, the equation could be written: 458 - 12 = x + 156 Solve the equation: x = 220 Therefore, Xiao Ming reads an average of 220 pages a day.
Xiao Ming was reading a storybook. He had already read 40% of the book, and there were still 90 pages left. How many pages does this book have?
This book has a total of $90+40%<<20>>= 1620$pages. Of which, 40% of the pages were already read by Xiao Ming, and the remaining 90 +80=170 pages were unread.
Xiao Ming was reading a storybook. He had already read 40% of the book, and there were still 90 pages left. How many pages does this book have?
This book has a total of $90+ 40%$ $×$pages. Substituting 40% into the above formula: $90+04×$ $×$pages = $90+04×$ $×$ (100-90) = $90+04×$ $× $10 = $90+04×$ $× $100 = $90+40=130$pages Therefore, the book had a total of 130 pages.
Xiao Ming reads 12 pages of the storybook every day. If he has read for a day, how many pages has he read? How many pages were left?
Xiao Ming had already read page 12a, and there were still pages 108- 12a left.😋I recommend a novel about transmigration and cultivation to you. It's called "The Mountain Man Has His Own Plan."

Little Ming was reading a storybook. He planned to read 12 pages a day, but he actually read 8 pages a day. In the end, he finished reading it two days earlier. How many pages is this storybook?
Xiao Ming planned to read 12 pages a day, but he actually finished reading 8 pages a day two days earlier. Assuming that this storybook has x pages: - The plan is to read x/12 days, which is x/12 pages. - Actually, x/8 days is x/8 pages. Because Little Ming finished reading it two days earlier, he only needed to read x/8 - x/12 = x/4 days. Because Xiao Ming reads 8 pages a day, he needs to read x/4 days x 8 pages = x 4/5 pages. Therefore, we can get the following equation: x/4 - x/12 = x/5 By solving this equation, one could obtain: x/12 = x/5 + 1/2 x/12 = (x+10)/5 x/12 = x/5 + 1/6 x/6 = 1/6 x = 1 Therefore, this storybook had one page.
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。
