Xiao Hong read a book. On the first day, she read one-fifth of the total number of pages. On the second day, she read another 30 pages. There were still 42 pages left. How many pages were there in this book?
On the first day, Little Red had read one-fifth of the total number of pages, which was one-fifth of the page. The next day, he read another 30 pages, so the remaining pages were the total number of pages minus 30 pages: 42 - 30 = 2 pages Therefore, the total number of pages in this book was five.
Xiao Hong read a novel. On the first day, she read 9 pages more than 1/12 of the total number of pages. On the second day, she read 7 pages less than 1/8 of the total number of pages, leaving 93 pages.
The total number of pages Little Red read on the first day was (12+9)/(12×1+9)= 13 pages. The total number of pages Xiao Hong read the next day was (13-7)/(8×1+7)= 9 pages. The number of pages Little Red read the next day was 7 pages less than the first day, and the remaining pages were 9 pages more than the first day. Therefore, the total number of pages she read the next day was 9/7 times that of the first day, which meant that she read 18 pages the next day. According to the total number of pages read on the first day and the total number of pages read on the second day, the total number of pages of the novel could be calculated as:13+9+18=40 pages. Therefore, the novel that Little Red was reading was the 40-Page Fictions.
Wang Hong read a book. On the first day, he had read 3/7 of the total number of pages. On the second day, he had read 1/4 of the total number of pages. How many pages of the book had he not read?
Wang Hong read a book on the first day, read 3/7 of the total pages, and the next day, read 1/4 of the total pages. How much of the book was left? Answer: The total number of pages in the remaining books is 3/7 of the total number of pages plus 1/4, which means the total number of pages is 8/7 plus 1/4, which is 9/11. Therefore, Wang Hong still had 9/11 of the book to read.
A book had a total of 95 pages. Xiao Hong read 13 pages a day. Could she finish it in a 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.
Xiao Hong read a book. On the first day, she read 25% of the total pages of the book. On the second day, she read two-fifths of the total pages of the book. There were still 35 nights left.
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.
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.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?
The total number of pages in this book is x. On the first day, I read three-fifths of the total number of pages, which is 3/5x pages on the first day. Reading 20% the next day meant reading 20% x 3/5 x = 2/5 x pages. Because he read 2/5x pages the next day, the remaining pages were 1 - 2/5x = 3/5x pages. Because Kobayashi read 3/5x pages, the total number of pages Kobayashi read was 3/5x + 2/5x = 5/5x pages. And because there were still 20 pages left in Kobayashi's book, 20 = 3/5x + 2/5x solved the equation to get x = 120. So this book has 120 pages.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?
Let the total number of pages in this book be x pages: - I read 3/5x pages on the first day. -20% read the next day =02x pages. According to the meaning of the question, the remaining pages were x-(3/5x+02x)=20 pages. Substituting x=50 pages gives: - I read 3/5 x 50 pages =30 pages on the first day. - The next day, I read 02 x 50 pages =10 pages. Therefore, the book had a total of 50 pages.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages, and on the second day, he read 20%. How many pages is this book?
