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.
On the first day, Xiao Hong read 25% of the total number of pages in the book, which was 1/4. The next day, Xiao Hong read half of the book's pages, which was 1/8. The remaining pages were 35% of the total number of pages in the book, which was 1/4 * 35% = 75%. Thus, the book had a total of 160 pages.
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 Xiao was reading a book. On the first day, she had read three-eighths of the book. On the second day, she had read the remaining two-fifths. There were still 36 pages left. She asked if there were any pages in the book.
The book had a total of 36 pages. On the first day, he read three-eighths of the book, which was 36 pages/8 = 4 pages/day. The next day, he read the remaining two-fifths, which was 36 pages/(2 + 5) = 4 pages/day. Since there were 36 pages left, the book had a total of 36 pages + 4 pages/day = 36 pages + 8 pages/day = 44 pages. Therefore, this book had a total of 44 pages.
A book had a total of 95 pages. Xiao Hong read 13 pages a day. Could she finish it in a week?
No. He read 13 pages a day for a total of seven days a week. Therefore, Little Red needed 7 * 13 = 91 pages to complete the reading mission for a week. However, a book has a total of 95 pages, so Little Red needs to read 91 pages.
Xiaoling read a novel. On the first day, she read 24 pages. On the second day, she read three-eighths of the total number of pages. There were still 36 pages left. How many pages does this book have?
Let the total number of pages in this book be x: - I read page 24 on the first day - The next day, I read three-eighths of the total number of pages, which is 24/8×3=13 pages. - 36 pages left Therefore, the book had a total of x+36 pages. Substituting x= total number of pages gives: x+36 = total pages Solve the equation: Total pages = 36 Therefore, the book had a total of 36 pages.
If you read 20% of the book on the first day, 25% of the total pages on the second day, and there are 110 pages left, how many pages are there in the book? stated
Let the total number of pages in this book be x pages. Reading 20% of the book on the first day meant reading 20% * x pages, which was 02x pages. The next day, he read 25% of the total number of pages, which meant that he read 25% * x pages, which was 025x pages. There were 110 pages left. According to the above calculation, the equation can be listed: 02x + 025x + 110 = x Solve this equation: 3x = 110 x = 33 Therefore, the total number of pages in this book was 33.
Naughty read a storybook. On the first day, he read 40% of the total pages. On the second day, he read 24 pages less than the first day. There were still 56 pages left. This book…
The total number of pages in this book is 100 pages. On the first day, I read 40 pages. On the second day, I read 24 pages less than the first day. Therefore, the number of pages I read on the second day is the number of pages I read on the first day plus 24 pages. The next day, he read 40 + 24 = 64 pages. So the total number of pages in the book was 100. Naughty read 40 pages on the first day and 64 pages on the second day. The remaining pages were 100 - 64 = 36 pages. On the first day, Naughty had read 40% of it, which was four pages. The next day, he read page 64/4 = 14. Therefore, the number of pages left for Naughty was 36 - 14 = 22. So, in the end, Naughty finished reading 22 pages, which was four pages less than the first day.
Xiao Gang read a book. On the first day, he read 30% of the total number of pages. On the second day, he read 4 pages less than the first day. There were 44 pages left. How many pages were there in this book?
Let's say the book has x pages. 30% read on the first day = 03x pages, the remaining pages are x-03x = 07x pages. The next day, I read 4 pages less than the first day, so I read 07x-4 pages the next day. According to the meaning of the question, the remaining pages are 44 pages, so there are: 07x-4 = 44 Solve the equation: 07x = 48 x = 64 So this book has 64 pages.
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.
If you read a book, you can read a quarter of the book on the first day, and two-fifths of the book on the second day. There are still 14 pages left. How many pages are there in this book?
Suppose the book has x pages. On the first day, he read a quarter of the book, which was 1/4 * x page of the book. The next day, he read two-fifths of the book, which was 1/4 * x pages, 2/5 = 5/16 * x pages. There were still 14 pages left, so: 14 ÷ (5/16 * x - 1/4 * x) = 14/(1/4 * x - 1/4 * x) = 14/(1/16 * x - 1/16 * x) = 14/(5/8 * x) = 14/(1/8 * x) To simplify it: 14/(1/8 * x) = 14 So 8 * 14 = x Solution:x = 96 So this book had a total of 96 pages.
A 180-page book, read two-fifths of the total, the next day read one-third of the total, how many pages are left
If a book had 180 pages and two-fifths of the total number had been read, then there would be 180 × 2/5 = 72 pages left. The next day, he read one-third of the total, so he had 180 × 3/10 = 24 pages left. Therefore, there were 72 + 24 = 106 pages left in the book.
