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.
A storybook has a total of 100 pages. The number of pages that have been read is four times the number of pages that have not been read. How many pages have been read? How many pages are left?
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.
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.
Xiao Xiao read a book, the 210 pages of the story book, the number of pages that have been read is 75% that have not been read, how many pages do you have left?
I need more context to answer this question. Please provide me with more details about the story and how Xiaoxiao read the book so that I can better answer your questions.
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.
Little Ding Ding reads a book with a total of 170 pages. The number of pages that have been read is 10 pages more than the remaining 3 times, so how many pages are left?
Assuming that the number of pages that Little Ding Ding had read was x, the remaining pages were 170-x. According to the conditions in the question, the number of pages seen is 10 pages more than the remaining pages. The following equation can be listed: x = (170 - x) + 10 To simplify it: 2x = 180 x = 90 Therefore, the number of pages that Little Ding Ding had read was 90, and the remaining pages were 170-90=80. Therefore, Little Ding Ding still had 80 pages left to 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.
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.
How many pages? How many pages does this novel have? If the ratio of the number of pages that Xiaofang has read to the number of pages that she has not read is 2:5, then reading 27 more pages will take up exactly half of the book?
The book had a total of 108 pages.😋I recommend a novel called Dream Casting 2005. It tells the story of programmer Lin Fan returning to 2005. In this life, he wants to go further and see more scenery. The book had a total of 108 pages, which seemed to be able to satisfy Xiaofang's requirement that the ratio of the number of pages she had read to the number of pages she had not read was 2:5. She had to read 27 pages, which was exactly half of the novel. I hope you like this fairy's recommendation. Muah ~😗
