A book has 200 pages. How many pages are left after reading 40%?
If a book has 200 pages and you've read 40% of it, then the remaining pages are: 200 pages × 04 = 80 pages Thus, there were still 80 pages left in the book.
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.
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.
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 has a total of 90 pages. After reading for 2 days, there are still 30 pages left. How many pages does Xiaohua read every day?
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.
If you read 20% of the book on the first day, 25% of the total pages on the second day, and there are 110 pages left, how many pages are there in the book? stated
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.
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.
