Xiao Hong read a 60-page storybook. On the first day, she read one-fifth of the book, and on the second day, she read one-fourth of the book.
On the first day, Xiao Hong read one-fifth of the book, which was 60 pages x 1/5 = 12 pages. The next day, Xiao Hong read a quarter of the book, which was 60 pages x 1/4 = 15 pages. Therefore, Little Red read a total of 12 + 15 = 27 pages on the first and second day.
Xiao Hong read a storybook. On the first day, she read 30 pages, which happened to be a quarter of the book. On the second day, she read a third of the book.
The next day, Little Red finished reading 30 pages of the book. The remaining pages were 1-1/4=3/4 pages of the book. On the first day, Little Red finished reading 1/4 of the book. The remaining pages were 3/4-1/4=1/4 pages. The next day, Little Red finished reading 1/4 of the book. The remaining pages were 1/4-3/4=1/4 pages. Therefore, Little Red finished reading 1/4+1/4=1 page of the book in two days.
Xiao Xiao read a book, on the first day, she read 55 pages, the next day, she read one-fifth of the whole book, at this time, the difference between what she had read and what she had not read was
Number of pages viewed/total pages = Number of pages viewed/total pages × 100% Total pages = 55 pages + one-fifth of the book = 55 pages + 25 pages = 80 pages Number of pages viewed/total pages = number of pages viewed/80 pages × 100%= 075 Therefore, when Xiao Xiao read a book on the first day, she would read 55 pages, and the next day, she would read one-fifth of the book. The ratio of what she had read to what she had not read was about 75%.
Xiao Gang read a story book. On the first day, he read one-fifth of the book, and on the second day, he read 40% of the book.
As a fan of online literature, I can provide you with the following information about this book: Reading one-fifth of the book on the first day and then reading 40% of the book on the second day meant reading 40% of the book on the second day instead of 5/1 = 20% of 40%. Therefore, Xiao Gang had read 15% and 20% of the book on the first and second day. He still had 75% of the book left. If Xiao Gang wanted to finish reading the book, he would need to continue reading until he reached 75% of the book.
Little Min read a 900-page storybook. On the first day, she read 124 pages. On the second day, she read 37 pages less than the first day. On the third day, which page should she start reading?
Little Min read a 900-page storybook, and on the first day, she read 124 pages. On the second day, she read 37 pages less than the first day. Assuming Min reads x pages the next day, the number of pages left on the second day is 900-x. According to the first day of reading page 124, the following equation can be listed: 124 + x = 900 - x + 37 Solve the equation: 151 = 867 Therefore, the number of pages that Little Min read on the third day should be a multiple of 867. Since 900 is an even number, 867 is a multiple of 900, so Min should start reading from page 867.
Zhao Jun read 30% of a 450-page detective novel on the first day. The next day, I read one-fifth of the book.
Zhao Jun read 30% of a 450-page detective novel on the first day. The next day, he read one-fifth of the book. Zhao Jun finished reading 30% of the book on the first day, which was 150 pages. The next day, he finished reading one-fifth of the book, which was 25 pages. Therefore, Zhao Jun only remembered 25 pages of the book that he finished reading the next day, which was 1/5 of the total number of pages. Zhao Jun read a 450-page detective novel. He finished 30% of the book on the first day and one-fifth of the book on the second day. He memorized 150 and 25 pages of the book.
Xiao Xiao was reading a 96-page storybook. On the first day, she had read 1/4 of the total number of pages. On the second day, she had read 3/8 of the total number of pages. On the third day, which page should she start reading?
According to the knowledge of online literature enthusiasts, we can calculate that 1/4 of the total number of pages read on the first day is 96 pages/4 = 24 pages. The next day, he read 3/8 of the total number of pages, which was 96 pages/8 = 12 pages. Hence, the number of pages Xiao Xiao had left on the first night was 96 - 24 - 12 = 62 pages. In that case, Xiaoxiao should have started from page 62, which was the remaining pages from the first day. Therefore, he should start reading from page 62 on the third day.
Xiao Hong read a book. On the first day, she read one-fifth of the total number of pages. On the second day, she read another 30 pages. There were still 42 pages left. How many pages were there in this book?
On the first day, Little Red had read one-fifth of the total number of pages, which was one-fifth of the page. The next day, he read another 30 pages, so the remaining pages were the total number of pages minus 30 pages: 42 - 30 = 2 pages Therefore, the total number of pages in this book was five.
Xiao Ming read a 480-page storybook and read page A every day for 12 days. How many pages are left?
When Xiao Ming read page A of the storybook every day for 12 days, he had read a total of 12 × page A. Therefore, when Xiaoming reads a 480-page storybook, he still has 480 - 12 × a pages left. To calculate the remaining pages, he needed to know how many pages Xiao Ming read in the end and how many pages he read every day. If we assume that the last page that Xiao Ming read was 480 pages and he reads page a every day, then we can write the following equation: 480 - 12 × a = Remaining pages By solving this equation, we can get: Remaining pages = 480 - 12 × a = 480 - 12a Therefore, after reading page A for 12 days, Xiao Ming still had 480 - 12A pages left.
A book has 360 pages. Congcong read one-fifth of the book on the first day, and read the first place on the second day
Congcong read 1/5 of the book on the first day. The number of pages he read the next day was equivalent to 1 of the entire book because there were 360 pages in the entire book. The number of pages he read the next day was 360 + 1 = 360. Therefore, the number of pages that Congcong read the next day was 1/1 of the entire book, which was 1/1 = 1.
Xiao Qiang read a storybook and read 20 pages a day. After five days, he still had one-fifth of the book left unread. How many pages was this storybook?
Let's say this storybook has $x$pages. He reads $20$pages every day, so Cockroach reads $20/times 5 = 100$pages. The remaining pages were one-fifth of the book, which was $025 x = 100$. The solution is $x = 400$. So this storybook is $400$pages.
