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.
A book has 128. Lingling read a quarter of the book on the first day. How much did she read on the first day?
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.
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.
If you read a book, you can read a quarter of the book on the first day, and two-fifths of the book on the second day. There are still 14 pages left. How many pages are there in this book?
Lingling read an eighth of the book on the first day, a quarter more on the second day, and eight more pages on the third day.
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.
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 book. On the first day, he read six pages. After that, he read four more pages every day. On the third day, he read two-fifths of the book and continued to read.
Xiao Hua reads a book on the first day, reads six pages, then reads four more pages every day, and on the third day, he reads two-fifths of the book. According to the question description, Little Light read four more pages every day than the previous day, so the total number of pages per day was the total number of pages on the previous day plus four pages. Therefore, after Little Light read six pages on the first day, the number of pages he read every day was the number of pages from the previous day plus four pages, which was six pages + four pages = ten pages. From the second day onwards, Little Light read four more pages a day than the previous day. Therefore, the number of pages he read every day was the number of pages from the previous day plus four pages, which was 10 pages + 4 pages + 4 pages = 16 pages. By analogy, we can find that when Little Light reads to the n-th day, the number of pages Little Light reads every day is the number of pages from the previous day plus 4 pages, which is n-pages + 4 pages. Therefore, by the third day, Little Light had read 2/5 of the book, which was 32 pages + 4 pages = 36 pages. Therefore, after the third day, Little Light still had 16 pages left to read. The total number of pages in the book was 36, so Little Light needed to read another 16 pages to finish reading.
Xiaoming read a story book, Xiaofang read a science book. The number of pages in a story book was 75% of that in a science book. Xiaoming read 15 pages a day, Xiaofang read 18 pages a day...
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.
Reading a 40-page story book, on the first day, you read three-eighths of the book, and on the second day, you read two-fifths of the book.
On the first day, he read three-eighths of the book, which was 40 × 3/8 = 15 pages. The next day, he read two-fifths of the book, which was 40 × 2/5 = 8 pages. Therefore, the answer was that he read eight pages the next day.
