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.
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.
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.
Xiaodong read a book. On the first day, he read one-fifth of the book, and on the second day, he read 15 pages. In this way, he read the whole book in two days
Xiao Dong read a fifth of the book on the first day and 15 pages on the second day. In two days, he read 15 times the book. Therefore, he had read the entire book in two days, 3/2 = 15 times. Then the book had a total of $pages × 15 = (pages + 15)+2 $pages.
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.
Li Yun read a book. On the first day, he read 24 pages. On the second day, he read one-fifth of the book. In two days, he read one-third of the book. How much did you see the next day?
The next day, he read one-fifth of the book, which was page 24/5 = 48. He read a third of the book in two days, which was 24 + 48 = 72 pages. Therefore, he read page 48 the next day.
Xiao Hong read a 60-page storybook. On the first day, she read one-fifth of the book, and on the second day, she read one-fourth of the book.
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.
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.
Xiao Lin read a book. On the first day, he read one-fifth of the book. On the second day, he read the remaining one-half. There were still 80 pages left. How many pages does this book have?
The book had a total of $80+2×5=130$pages. Of which,$2$meant that Kobayashi read half of the book the next day. Since he read the remaining half the next day, the remaining part was $1-1/2=1/2$times the book, which was $1/2×130=65$pages. I read one-fifth of the book on the first day, so the book has a total of $130+5/4=185$pages.
Xiao Lin read a book. On the first day, he read one-fifth of the book. On the second day, he read the remaining one-half. There were 80 pages left. He didn't know how many pages the book had.
The book had a total of $80+ 5'times 2=130$pages. On the first day, he read one-fifth of the book, which meant that the remaining pages were $130,5 =26$. The next day, he read the remaining half of the book, which meant that the remaining pages were $26> times 2=52$. Therefore, the book had a total of 130 pages.
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.
