Xiao Xiao was reading a 150-page book. She had read two-fifths of the book in four days. How many pages were left?
Xiao Xiao read a 150-page book for four days and read two-fifths of the book. Xiaoxiao reads 1/5/4 = 1/10 of the book every day The book had 150 pages, so Xiaoxiao still needed to read pages 1 - 1/5 - 1/10 = 4/5. And because Xiaoxiao had already read two-fifths of the book, there were still four to five pages left. Hence, Xiao Xiao still needed to read 2/5 pages.
Xiao Xiao was reading a 150-page book. She had already read two-fifths of the book. How many pages were left?
If Xiaoxiao had already read two-fifths of a 150-page book, then she had already read 150 × 2/5 = 60 pages. The remaining pages were 150 - 60 = 90 pages. Hence, Xiao Xiao still had 90 pages to read.
Xiao Ming was reading a 200-page storybook. He had already read two-fifths of the book and had 10 more pages. How many pages were left?
Xiao Ming had already read two-fifths of a 200-page storybook, which was 10 pages more. 200 pages × 2/5 + 10 pages = 40 pages The remaining pages were: 200 - 40 pages = 160 pages Therefore, Little Ming still had 160 pages left.
Xiao Hong had already read 40 pages of the book, which was exactly two-fifths of the book. How many pages were left?
If Xiao Hong had already read 40 pages of a book, which was two-fifths of the book, then Xiao Hong had already read 20% or 0.2 times the book. How many pages are there in the book? You can divide the number of pages by the number of pages in the book: (100% - 02) / 100% = 90% Therefore, Little Red only had 10 pages left.
Xiao Ming is reading a 150-page storybook. He has already read two-fifths of the book. How many pages are left?
Xiao Ming had already read two-fifths of a 150-page storybook, so he had already read 150 × 2/5 = 60 pages. Therefore, there were still 150 - 60 = 90 pages left in the storybook.
Xiao Xiao was reading a book. On the first day, she had read three-eighths of the book. On the second day, she had read the remaining two-fifths. There were still 36 pages left. She asked if there were any pages in the book.
The book had a total of 36 pages. On the first day, he read three-eighths of the book, which was 36 pages/8 = 4 pages/day. The next day, he read the remaining two-fifths, which was 36 pages/(2 + 5) = 4 pages/day. Since there were 36 pages left, the book had a total of 36 pages + 4 pages/day = 36 pages + 8 pages/day = 44 pages. Therefore, this book had a total of 44 pages.
A book had 170 pages. Xiaowen had read two-fifths of it. How many pages were left?
Xiaowen had read two-fifths of the book, which meant that Xiaowen had read 2/5 * 170 = 48 pages. Therefore, there were still 170 - 48 = 122 pages that he had not read.
Xiao Dong read a 420-page book. He read 26 pages a day. After reading for 13 days, how many pages were left?
Xiao Dong read a 420-page book. He read 26 pages a day, and after 13 days, there were still pages left. The calculation process was as follows: The total number of pages he read in 13 days was 26 * 13 = 336 pages. The total number of pages in this book is 420, so the total number of pages needed to read the whole book is 420. Therefore, the number of pages Little Dong needed to finish reading the book in 13 days was 336 pages/13 days = 26 pages/day. Because Xiao Dong read 26 pages every day, the total number of pages he read every day was 26 + 26 = 52. Therefore, the number of pages Little Dong needed to finish reading the book in 13 days was 52 pages/13 days = 4 pages/day. Because Xiao Dong read four pages a day, the remaining pages were 420 - 4 * 13 = 420 - 52 = 368. Therefore, Xiao Dong still had 368 pages to read.
Little Ming was reading a 30-page book, and he had already read two-fifths of it. How many pages were left?
Xiao Ming had already read two-fifths of a 30-page book, so there were 30 - 2/5 = 30 - 04 = 296 pages left. Therefore, there were 296 pages left in the book.

Xiao Hong had read a book. She read 24 pages a day. After five days, she still had 40% of the book left. How many pages was this book?
Little Red read 24 pages a day for 5 days, so how many pages did she read in total: 5 days x 24 pages/day = 120 pages The rest of the book takes up 40% of the whole book, so the remaining pages take up: 40% ÷ 100% = 04 The pages of the book were: 120 pages/04 = 300 pages So this book has 300 pages.
