The number of pages read in a book was the remaining 75%. How many pages did the book read account for? How many pages were left?
If the remaining 75% of the pages of a book were read, it meant that 75% of the pages had not been read. Then, the number of pages that were read would be 25%+80% = 3/4. The number of pages left is a fraction of the number of pages seen. It can be calculated in a similar way: the number of pages left is 1 -the number of pages seen = the number of pages left-the number of pages seen = 75% x the number of pages left divided by the total number of pages. Therefore, the remaining pages were 75% of the total number of pages. The answer was that the remaining pages were 75% of the number of pages read divided by the total number of pages.
There are 420 pages in a book. The number of pages that have been read is the remaining 3/4. How many pages are left?
Assuming that there were still x pages left, the number of pages that had been read would be 420 - x. According to the question, the number of pages that have been read is the remaining three-quarters, so the following equation can be written: 420 - x = 3/4 (420 - x) To simplify it: x = 396 Therefore, there were still 396 pages left.
There are 200 pages in a book. The number of pages that have been read is the remaining 60%. How many pages have you read?
If the number of pages seen is x, the remaining pages are 200-x. According to the meaning of the question, the equation can be listed: x = 60% (200-x) To simplify it: x = 60% × 200 - 60% × x To solve the equation: 120 - 30% × x = 200 30% × x = 80 x = 240 Therefore, the number of pages he had seen was 240.
Xiao Li read a book. The number of pages she had read was half of the number of pages she had not read. She read another 30 pages. At this time, the number of pages she had not read was three sevenths of the number of pages she had read. How many pages were there in this book?
This book has a total of $30+ 30> times 3/7=60$pages.
Little Light was reading a book. The number of pages she had read was 4/5 of the number of pages she had not read. After dinner, she read another three pages. At this time, the number of pages she had read was 5:6. How many pages was this book...
Let's say the book has x pages. According to the meaning of the question, Little Light had already read 4/5 of page x, which meant that 4/5 x = 3 solved x = 3 × 5/4 = 15/2. The ratio of the number of pages that had been read was 5:6, which was 5/6 × 15/2 = 25/12. Because Little Light had read three more pages, the page ratio was 5:6, which was 25/12 = 5/8. The solution is x = 2425 because the total number of pages in the book must be an entire number, so this book has 24 pages.
I have read 8 pages of a book, and the number of pages that I haven't read is 4 times that of reading. How many pages does this book have?
Suppose the book has x pages. Since he had already read 8 pages, the remaining pages were x - 8. In addition, the number of pages in the book was four times the number of pages read, which meant that the remaining pages were 4x. According to the meaning of the question, we can list the equation: x - 8 = 4x Solve the equation: 2x = 8 x = 4 Therefore, this book had a total of four pages.
Three fifths of a book has been read, and there are 15 pages left. The number of pages read is a fraction of the number of pages not read
If a book has been read three-fifths of the way and there are 15 pages left, then the number of pages read is the number of pages not read: Number of pages seen/number of pages not seen = 3/5/4/5 = 3/4 Therefore, the number of pages that had been read was four-thirds of the number of pages that had not been read.
Ding had read 300 pages of a book, which was 27 pages less than the number of pages he had not read. How many pages were left?
Assuming that the book has a total of n pages, then the ones that Ding has not read are n-300 pages. According to the question, Ding read 300 pages more than he did not. n - (n-300) = 300 To simplify it: 2n - 300 = 300 2n = 300 + 300 2n = 600 n = 300 Therefore, the book had a total of 300 pages. Little Ding had already read 300 pages, but he hadn't read 300-300=0 pages. Hence, there were still 0 pages left.
There were 150 pages in a book, and he had already read 38 pages. How many pages would he read in the remaining seven days?
He had already read 38 pages, so the remaining pages were 150 - 38 = 112 pages. In order to finish reading these 112 pages, he had to read 112/7 = 16 pages every day. Therefore, he read an average of 16 pages a day.
How many pages did he read when he read two-thirds of the 170 pages of the book?
The book had a total of 170 pages. Two-thirds of it was equivalent to 70 pages. The remaining three-quarters were equivalent to 40 pages. Therefore, he had read 170 pages in total, and he needed to read the remaining 40 pages twice, which was 70 pages.
