how to read a book a day
Xiao Ming read a book. On the first day, he read 10% of the book, the second day, he read 35%, and the third day, he read 44 pages. This book…
How many pages are there in this book?
According to the title, Xiaoming read 10% of the book on the first day, which was 10% of the book divided by 100% = 1/10 pages.
Xiao Ming read 35% of the book the next day, which was 35% of the book divided by 100% = 035 pages.
Xiao Ming read 44 pages of the book on the third day, so the number of pages in the book can be calculated by the following formula:
1 ÷ (1/10 + 035 + 1/10) = 44
Solve the equation:
Number of pages in the book = 44 × 100%/(1 + 035 + 1) = 3520
Therefore, this book had a total of 3520 pages.

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 Light read a story book. On the first day, he read a quarter of the book, and on the second day, he read a fifth of the book. On the first day, he read 10 more pages than the second day.
If the total number of pages in the storybook was X, then Little Light would read a quarter of the book on the first day, which was X/4 pages, and a fifth of the book on the second day, which was X/5 pages.
According to the topic, the first day was 10 pages more than the second day, so there were:
(X/4 - X/5) = 10
To simplify it:
X/10 = 10
X = 100
Therefore, the total number of pages in the storybook was 100.
Little Light read 100/4 = 25 pages on the first day and 100/5 = 20 pages on the second day. He read 45 pages in total.

When you read a book, you read one-fifth of the book on the first day, and you read one-fourth of the book on the second day, and you read 30 more pages on the first day than the second day.
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.

Xiaodong read a book. On the first day, he read 3/5 of the book, and the next day he read 20 pages. At this time, he had read the number of pages in the book.
Xiao Dong read 3/5 of the book on the first day, which was 0.6 times the volume of the book.
The next day, he read another 20 pages, which was equivalent to 1/5 of the entire book, which was 0.2 times the volume of the entire book.
Therefore, the number of pages Little Dong had read was:
The number of pages read = the volume of the book x the number of days read-the total number of pages
= 06 × volume of the book × 1 - 02 × volume of the book
= 02 × the volume of the book
Since the total number of pages in the book did not change, the number of pages that Xiao Dong had read was 0.2 times that of the book.

Xiao Lin read a book. On the first day, he read 1/5 of the book. On the second day, he read 4/9 of the book. At this time, there were still 32 pages left.
Kobayashi read 1/5 of the book on the first day and 4/9 on the second day. The remaining pages were:
32 pages/(1 - 1/5) - 32 pages = 32 - 32 pages/4/9 = 32 - 48 pages/1/5
Next, Kobayashi needed to convert the remaining pages into whole pages and calculate:
32 - 48 pages/1/5 = 160 - 192 pages/4/9 = 160 - 384 pages/5
Since the number of pages and the number of pages were both whole numbers, the final result should be 160 - 384 = 112 pages.
Therefore, Kobayashi had already read 1/5 + 4/9 of the book before the next day, which was 11/45. The remaining pages were 32 pages. Kobayashi needed to finish these 32 pages by the next day to finish the book.

Ling Ling read a book. On the first day, she read one-fourth of the book. On the second day, she read three-sevenths of the book. On the second day, she finished reading the book in three 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.

When is the best time to read a book in a day?
The best time of day for reading varies from person to person, but generally speaking, people read best in the morning and evening.
This was because the human brain was still at a relatively low level in the morning. Reading could stimulate brain activity and improve memory and concentration. Reading at night could help the brain to rest better and avoid overuse, thus better absorbing new knowledge.
However, the choice of reading time also had to take into account other factors such as work, study, social activities, as well as personal habits and preferences. If you want to read, try to read at a fixed time every day to get a better reading experience and effect.

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.
