He had clearly read four-fifths of the story book, but there were still 16 pages left. How many pages was this book?
He had clearly read four-fifths of the storybook, and there were still 16 pages left to write the equation: He had clearly read 4/5 of the storybooks, and there were 16 pages left. 1 + 4/5 = 9/5 books Because I have read 4/5 storybooks, each storybook has: 4/5/1 = 8/15 pages Therefore, this book had: 9/5 × 8/15 = 96/15 pages It was about six pages.
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.
Xiao Hong read a book and read 15 pages a day. After four days, she still had three-fifths of the book left. How many pages was this book?
Let's say the book has $x$pages. Reading 15 pages a day, it would take Xiaohong $x$days to finish reading this book. The remaining pages were three-fifths of the book, which was $025x$. According to the question, it would take Xiaohong four days to finish reading this book. Therefore, we can write the equation: $$ x + 025x = 025 \times (x+4) $$ Solve this equation: $$ x = 30 $$ So this book has 30 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.
