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.

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.

Ling Ling read a book on the first day, a quarter of the book, the next day, three-sevenths of the book, and the next day: The next day, Ling Ling spent about four-sevenths of the time reading the book. In other words, she had read 4/7 of the book and still had 3/7 left. Since she only had three days, she needed to finish the book as soon as possible. Therefore, she decided to read 7/8 of the book on the second day, which was the remaining 1/8. Therefore, Ling Ling spent about 1/8 of her time reading the book the next day, leaving 7/8 - 1/8 = 6/8. She could continue reading until she finished reading in the remaining 1/8 of the time.

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%.

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.

Assuming that the book has $x$pages, reading one-fifth of the book on the first day means reading $/frac{1}{5}x$pages, then reading one-quarter of the book on the second day means reading $/frac{1}{4}x$pages. According to the fact that we read 30 more pages on the first day than the second day, we can write the equation: $$ \frac{1}{5}x - \frac{1}{4}x = 30 $$ By solving this equation, one could obtain: $$ x = 150 $$ So this book has 150 pages.

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.

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.

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.
