Xiao Gang read a book. On the first day, he read 30% of the total number of pages. On the second day, he read 4 pages less than the first day. There were 44 pages left. How many pages were there in this book?
Let's say the book has x pages. 30% read on the first day = 03x pages, the remaining pages are x-03x = 07x pages. The next day, I read 4 pages less than the first day, so I read 07x-4 pages the next day. According to the meaning of the question, the remaining pages are 44 pages, so there are: 07x-4 = 44 Solve the equation: 07x = 48 x = 64 So this book has 64 pages.
Xiao Ming read a book. On the first day, he read 1/6 of the book, the second day, he read 24 pages, and the third day, he read the total number of pages in the previous two days.
Xiao Ming read a book on the first day, he read 1/6 of the whole book, the second day, he read 24 pages, the third day, he read the total number of pages in the previous two days If he read 24 pages the next day, he would read (24 div6) = 4 pages the next day. The rest of the books had 5/6 pages. Xiaoming read 1/6 pages on the first day, so he read (5/6 div1/6) = 30 pages on the first day. Xiao Ming's remaining book had 1/6 pages. The number of pages he read the next day was 4 + 30 = 34. Xiao Ming's remaining book had 1/6 pages. The number of pages he read on the third day was 34 + 24 = 58. Therefore, on the third day, Xiao Ming read the entire book's 58 + 6 = 9 pages.
Xiaoming reads a book on the first day, reading 20% of the total number of pages, the number of pages read on the second day and the number of pages read on the first day is 5:4
Xiao Ming read 20% of the total number of pages on the first day of reading a book, which means that the total number of pages multiplied by 20% equals 20% of the total number of pages. On the second day, the ratio of pages read on the first day was 5:4, which meant that half of the total pages read on the second day was 25% of the total pages. Therefore, Xiao Ming read the total number of pages multiplied by 25% the next day, which was equal to the total number of pages multiplied by 5%. Divide the total number of pages by 5 to get the number of pages that Xiaoming read the next day divided by 5. That is, the total number of pages divided by 5 multiplied by 40% equals the total number of pages multiplied by 10%. Therefore, Xiao Ming read the total number of pages multiplied by 10% the next day, which was equal to the total number of pages multiplied by 5.
Xiao Ming is reading a book. He had read 20% of the total number of pages on the first day. The number of pages read on the second day was 5:4 compared to the number of pages read on the first day. There were still 110 pages left to be read…
Xiao Ming reads a book on the first day, 20% of the total number of pages, and the number of pages read on the second day is 5/4 of the number of pages read on the first day, leaving 110 pages Assuming that the total number of pages in this book is x: I read 20% on the first day, which is 02x pages. I read 5/4x pages the next day because I read more pages the next day than the first day The remaining pages are x -02x- 5/4x = 110 pages Solve the equation: x = 1100 Therefore, the total number of pages in this book is 1100. Xiaoming read 200 pages on the first day and 300 pages on the second day.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages, and on the second day, he read 20%. How many pages is this book?
The information you provided is not detailed enough to determine the total number of pages in this book. Please provide more information so that I can answer your questions.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?
The total number of pages in this book is x. On the first day, I read three-fifths of the total number of pages, which is 3/5x pages on the first day. Reading 20% the next day meant reading 20% x 3/5 x = 2/5 x pages. Because he read 2/5x pages the next day, the remaining pages were 1 - 2/5x = 3/5x pages. Because Kobayashi read 3/5x pages, the total number of pages Kobayashi read was 3/5x + 2/5x = 5/5x pages. And because there were still 20 pages left in Kobayashi's book, 20 = 3/5x + 2/5x solved the equation to get x = 120. So this book has 120 pages.
Xiao Lin read a book. On the first day, he read three-fifths of the total number of pages. On the second day, he read 20%, leaving 20 pages. How many pages is this book?
Let the total number of pages in this book be x pages: - I read 3/5x pages on the first day. -20% read the next day =02x pages. According to the meaning of the question, the remaining pages were x-(3/5x+02x)=20 pages. Substituting x=50 pages gives: - I read 3/5 x 50 pages =30 pages on the first day. - The next day, I read 02 x 50 pages =10 pages. Therefore, the book had a total of 50 pages.
Wang Hong read a book. On the first day, he had read 3/7 of the total number of pages. On the second day, he had read 1/4 of the total number of pages. How many pages of the book had he not read?
Wang Hong read a book on the first day, read 3/7 of the total pages, and the next day, read 1/4 of the total pages. How much of the book was left? Answer: The total number of pages in the remaining books is 3/7 of the total number of pages plus 1/4, which means the total number of pages is 8/7 plus 1/4, which is 9/11. Therefore, Wang Hong still had 9/11 of the book to read.
Xiao Ming read a book. On the first day, he read 24 pages, which was exactly three-eighths of the total number of pages. On the second day, he read one-fourth. How many pages did he read on the second day?
Xiao Ming read a book on the first day, 24 pages, which is exactly three-eighths of the total number of pages. The next day, he read a quarter of the book. How many pages did he read the next day? On the first day, he had read 24 pages, which was three-eighths of the total number of pages, so he had read 24/8 × 3 = 5 pages on the first day. The next day, he read a quarter of the page. Therefore, the number of pages left on the second day was 24 - 5 - 1 = 19 pages.
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.
