Ling Ling read a quarter of the book on the first day, which was 128 div4 = 32. Therefore, Ling Ling read 32 pages on the first 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.
Lingling read a book on the first day, read one-eighth of the book, read a quarter more on the second day, and read eight more pages on the third day than on the second day. I read 1/8 on the first day. The next day, I read 1/8 × 1/4 = 1/24 On the third day, I read 1/8 × 1/4 + 8 = 1/24 + 8/4 = 9/24 Therefore, Ling Ling had read (1+9/24) = 17/24 pages in this book.
Zhang Li read a book of 80 pages. On the first day, she read 35% of the book, and on the second day, she read 1/4 of the book. How many pages did she read in two days? On the first day, he read 35% of the book, which was 80 pages x 35% = 28 pages. The next day, he read 1/4 of the book, which was 80 pages x 1/4 = 20 pages. Therefore, the total number of pages he read in two days was 28 + 20 = 48. Answer: 48 pages in two days.
Ling Ling spent three days to finish reading a story book, and on the first day, she read 25% of the book.
In the first week, Xiaowen had read a quarter of the book, which meant that she had read 1/4 of the book. In the second week, Xiaowen had read one-fifth of the book, which meant that she had read 1/5 of the book. The ratio of the remaining books was $1-1/4-1/5=16/20$. Because Xiaowen hadn't finished reading the entire book, she needed to look at the ratio of $16/20$, which was $8/20$. If the book has a total of $x$pages, then $x=16/20*165$. The solution is $x=2400$. So the book had a total of $2400 pages.
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.
Assuming the book has a total of n pages, Lili read 78 pages in the first 3 days, then there are still n - 3 × 78 = n - 262 pages not read. In the next four days, she read an average of 40 pages a day. In these four days, Lili read a total of 40 × 4 = 160 pages. Therefore, Lili had read a total of n - 262 + 160 = 322 pages, just enough to finish the book. So this book had 322 pages.
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.
The number of pages read is the number of pages read on the first day plus the 16 pages read on the second day. Number of pages viewed = 10/1 + 16 = 16 + 10/1 = 26 + 10/1 = 36 Therefore, Wang Ying had already read 36 pages.
