A book has a total of 90 pages. After reading it for two days, Little Light still has 30 pages left. 30 pages/2 days = 15 pages/day Because Little Light reads 15 pages of this book every day, the proportion of pages that Little Light reads every day is: 15/90 = 1/6 Therefore, Little Light read one-sixth of the book every day.
A story book has 235 pages. After reading it for ten days, Ling Ling still has 75 pages left.
After ten days, Lingling was left with 75 pages, so the average number of pages she read every day was: 75 pages/10 days = 75 pages/day As there were still 75 pages left, Lingling still needed to read them every day on average: 23 - 75 = -525 Because the number of pages was negative, Ling Ling had read the book many times after ten days, but she hadn't finished it.
A book with a total of 240 pages. Xiaolan has already read 2/3 of the total pages of the book. How many pages are left to read and write?
Xiaolan had already read 2/3 of the total number of pages in the book, so she had already read (2/3) × 240 = 80 pages. The remaining pages were 240 - 80 = 160 pages. Therefore, there were still 160 pages left to read.
Xiao Gang reads a story book every day and reads 56 pages. After reading for four days, there are still 3/11 pages left. How many pages is this book?
Let's say the book has $x$pages. Xiao Gang reads $56$pages a day, so the number of pages needed to finish the book in four days is $56/times 4 = 216$pages. The remaining pages are $3/11$of the book, which means that the remaining pages are $216/div3/11 = 80$pages. Because Xiao Gang still needed to read for four days, the total number of pages he needed to read was $80 + 4 = 84$pages. Therefore, the book has a total of $x = 84$pages.
Reading a storybook every day, 40 pages a day. After 3 days, there is still 5/8 of the Golden Book left. How many pages is this book?
Assuming the book has $x$pages: - $40$on the first day. - The next day, he read $40/times 2 = 80$pages. - On the third day, if you read $3/8$on $40$pages, you would read $10$pages. Because there was still $5/8 left, there was: $$ 40 + 80 + 10 = \boxed{120} $$ So this book has 120 pages.
Xiaofang has read 80 pages of a science book, and there are still 31 pages left. What she has read accounts for a few of the total pages of the book
The total number of pages in this book was 80 + 31 = 111. Therefore, the number of pages that Xiaofang had read accounted for the total number of pages in this book: 111 pages = 1 / 11 In other words, the number of pages that Xiaofang had read accounted for 1/11 of the total number of pages in the book.
Naughty is reading a storybook. He has read 5/7 of the total number of pages. There are still 40 pages left. How many pages does this book have? Trouble calculating!
Let's assume that the total number of pages in this book is x. Naughty had already read 5/7 of the total number of pages, which meant that he had already read 3/5 of x pages. Therefore, he still had 2/5 of x pages to read. There are still 40 pages to read, so the total number of pages that Naughty still needs to read is: 2/5 of x + 40 To simplify it: x + 40 / 5 The general score was: x + 80 Since x is the total number of pages: x + 80 = x / 5 + 80 To simplify it: x = 400 Therefore, the book had a total of 400 pages.
Huanhuan has already finished reading three-fifths of the total number of pages in the storybook. There are still 36 pages left. How many pages are there in this storybook?
The number of pages in a storybook can be expressed as $x$, so the total number of pages is $x \times 3/5$. Since there were still 36 pages to read, the total number of pages in the storybook plus these 36 pages was $x/times 3/5 + 36$. And because the book had a total of $x$pages, the equation could be listed: $$x \times 3/5 + 36 = x$$ If you solve this equation, you get $x=300$. Therefore, the story book had a total of $300$pages.
