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.
Zhang Li read a book with 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?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 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.
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.
