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.
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.
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.
I have read two-fifths of a book, and there are still 135 pages left to read. I want the number of pages in the whole book.
Suppose the book has x pages. It was known that two-fifths of the book had been read, and the remaining pages were 135. Therefore, he read this book in total: 135/(2/5 + 1) = 625/7/5 = 1275 pages. Since the total number of pages in the book is x, there are: x = 1275 pages. Therefore, the total number of pages in the book was: x = 1275 pages.
The number of pages that have been read is 1/7 of the number that has not been read
It was wrong to say that the number of pages that had been read was 1/7 of the number that had not been read. This was because when reading a novel, one would usually mark the number of pages in the process of reading, such as marking the number of pages at the end of each page or using a bookmark to record the parts that had been read. Therefore, the number of pages read and the number of pages not read may be different, but their ratio should be the same.
A book has 170 pages. Xiaowen has read two-fifths of it. How many pages are there left?
Xiaowen had read two-fifths of the book, which meant that Xiaowen had read 170 pages divided by 2 = 85 pages. There were still 170 - 85 pages = 85 pages that he had not read.
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.
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 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.
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. 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.
