Dongdong was reading a book with a total of 150 pages. At the end of the second week, he found that the number of pages he had not read was exactly the same as the number of pages he had read in the first week.
Dongdong read a total of x pages at the end of the first week. The total number of pages in this book is 150, so: At the end of the second week, Dongdong had read (150 - x) pages. Dongdong hadn't finished reading 150 pages by the end of the second week, so he had read (150 - x) pages less than or equal to 150 pages. And because Dongdong had read page X in the first week: x = 150 - x + 1 = 149 The solution was x = 1, so Dongdong read a total of 149 pages in the first week. Dongdong had read (150 - 1) = 149 pages by the end of the second week. Therefore, Dongdong read a total of 149 pages in this book, and there was still one page left at the end of the second week.
Xiao Hong read a book. In the first week, she read 30%. In the second week, she read 55 pages. At this time, the ratio of the number of pages read to the total number of pages was 2:3.
Xiao Hong read 30% in the first week and 55 pages in the second week. The ratio of the number of pages read to the total number of pages is 2:3. We can set the total number of pages of this book as x pages. According to the question, Xiao Hong had already read 30% of the first week, which was 03x pages. In the second week, she had read 55 pages, so she had already read 03x + 55 pages. The ratio of the number of pages seen to the total number of pages is 2:3, so there is: 03x + 55 = 2/3x Solve the equation: 13x + 55 = 2/3x 13x - 2/3x = 55 01x = 55 x = 550 Therefore, the total number of pages in this book was 550.
Xiaoming reads a book on the first day, reading 20% of the total number of pages, the number of pages read on the second day and the number of pages read on the first day is 5:4
Xiao Ming read 20% of the total number of pages on the first day of reading a book, which means that the total number of pages multiplied by 20% equals 20% of the total number of pages. On the second day, the ratio of pages read on the first day was 5:4, which meant that half of the total pages read on the second day was 25% of the total pages. Therefore, Xiao Ming read the total number of pages multiplied by 25% the next day, which was equal to the total number of pages multiplied by 5%. Divide the total number of pages by 5 to get the number of pages that Xiaoming read the next day divided by 5. That is, the total number of pages divided by 5 multiplied by 40% equals the total number of pages multiplied by 10%. Therefore, Xiao Ming read the total number of pages multiplied by 10% the next day, which was equal to the total number of pages multiplied by 5.

There is a book with a total of 200 pages. How many times does the number 2 appear in these pages?
The frequency at which the number 2 appears on the page number of each book depends on the format and arrangement of the page number. In the common page format, the number 2 usually appears around 10% of the time, but it can also be higher or lower. For example, if the pages of a book are arranged in chapter order and each chapter contains the number 2, then the frequency of the number 2 appearing in each chapter is 10%. In addition, if the pages of a book are arranged in page order, and each page contains the number 2, then the number 2 appears on one of every ten pages. Therefore, to calculate the number of times the number 2 appears in a 200-page book, you need to first determine the format and arrangement of the page numbers and then calculate the number of times the number 2 appears in every chapter or every 10 pages. The specific calculation method could be completed using a statistics software or online tools.

A book had a total of 95 pages. Xiao Hong read 13 pages a day. Could she finish it in a week?
Naughty has read more than one-fifth of the total number of pages in a book. Twenty-four pages and the remaining two-thirds of the total number of pages. How many pages are there?
Let's assume that the total number of pages in this book is x. The number of pages that Naughty had already read was x +5 + 24, which was a total of x +5+24. The remaining pages make up two-thirds of the total number of pages, so there are: x÷5+24 + x/2 = x The above formula was simplified: x/2 + 24 = x After the reduction, it was obtained: x/2 = 24 Solution: x = 48 Therefore, the total number of pages in this book was 48.
A book with a total of 240 pages. Xiaolan has already read 2/3 of the total pages of the book. How many pages are left to read and write?
Xiaolan had already read 2/3 of the total number of pages in the book, so she had already read (2/3) × 240 = 80 pages. The remaining pages were 240 - 80 = 160 pages. Therefore, there were still 160 pages left to read.
Xiao Ming is reading a book. He had read 20% of the total number of pages on the first day. The number of pages read on the second day was 5:4 compared to the number of pages read on the first day. There were still 110 pages left to be read…
Xiao Ming reads a book on the first day, 20% of the total number of pages, and the number of pages read on the second day is 5/4 of the number of pages read on the first day, leaving 110 pages Assuming that the total number of pages in this book is x: I read 20% on the first day, which is 02x pages. I read 5/4x pages the next day because I read more pages the next day than the first day The remaining pages are x -02x- 5/4x = 110 pages Solve the equation: x = 1100 Therefore, the total number of pages in this book is 1100. Xiaoming read 200 pages on the first day and 300 pages on the second day.
