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.
How many days has Xiaoming been watching? (Question symbol)
I've been reading for seven days, so I haven't read seven pages.
The remaining pages were 256 - 13 × 7 = 234 pages.
Therefore, Little Ming still had 234 pages to read.
There are 62 pages in a book that need to be written in 12 days. The answer can be obtained by calculating how many pages you need to write each day.
62 pages/12 days = 5 pages/day
Therefore, he had to write five pages a day. Please note that this is only an estimate. The actual writing speed may be affected by many factors such as the quality of the writing, the length of the article, etc.
If a book has 200 pages and 40 pages have been read, then the number of unread pages is 160.
The ratio of pages that have been read to the number of pages in the book is:40 pages/200 pages =02%.
Therefore, the answer for those who have read less than those who have not read is:02%-100%=002%. In other words, it was about 2% less than those who did not study.
The storybook has a total of 100 pages. The number of pages that have been read is four times that of the number of pages that have not been read.
The known number of pages seen = the number of pages seen + the number of pages left, which was 4 unseen pages = the number of pages seen + the number of pages left.
Transferring the items would yield 5 pages remaining = 4 pages viewed, which meant that the remaining pages = 4 pages viewed divided by 5.
Since the story book has a total of 100 pages, 4 pages viewed/5 = 8 pages remaining.
Thus, there were still eight pages left.
If a book has 137 page numbers, we can use the number of page numbers to estimate the total number of pages in the book.
Assuming that each page has x numbers, the page number of the book can be expressed as:
1 2 3 136 137
The first number represented page 1, the second number represented page 2, and so on.
Because there were 137 numbers in the page, the total number of the corresponding page number on each page was:
1 + 2 + 3 + + 136 = 137 x 136 = 19112
Therefore, this book had a total of 19112 pages.
Therefore, if a book has 137 pages, the book has 19112 pages.
After reading 12 pages on the first day, he read 6 more pages every day than the previous day. On the last day, he read 48 pages. How many days did he read in total?
He had read $12+12 + 12 + 12 + 12 +12+6+48$in total.
Reading 6 more pages a day than the day before, so obviously in the first week, I read $12+12 + 12 + 12 + 12 +12+6+12=55$days.
In the second week, he read $12+12 + 12 + 12 + 12 +12+6+12+12=63$days.
By analogy, we can know that the total amount of reading before the end of the book is $55+63+70+73+80+86+98+48=695$days. Therefore, he read for a total of seven days.
