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

2024-09-12 08:49

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 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.

When Xiaoming read a book, he would read 3/8 of the book on the first day and 18 pages on the second day. At this point, the number of pages read accounted for 3/5 of the total number of pages. How many pages are there in this book

Xiao Ming read 3/8 of the book on the first day, which was 042675 or 42675% of the book. The next day, he read 18 pages, and the remaining pages were 5/8 of the book, which was 075 or 75%. Suppose the book has x pages: 3/5 of the total number of pages read = (x * 3/8 + 18) / x = 3/5 To simplify it: x = 42 * 8 / 3 = 96 Therefore, the book had a total of 96 pages.

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.

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, 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.

The total number of pages in the book was $30+30=60$pages. The number of pages read is $2x$, and the number of unread pages is $3x$. where $x$is an integral number. On the first day, the ratio of pages read to unread was $2:3, so $2x=3x+30. The solution is $x=10$. Therefore, the number of pages read is $2x=20$, and the number of unread pages is $3x=30$. So this novel has a total of $60$pages, I've read $20$pages, I haven't read $30$pages.

The total number of pages in this book is 100 pages. On the first day, I read 40 pages. On the second day, I read 24 pages less than the first day. Therefore, the number of pages I read on the second day is the number of pages I read on the first day plus 24 pages. The next day, he read 40 + 24 = 64 pages. So the total number of pages in the book was 100. Naughty read 40 pages on the first day and 64 pages on the second day. The remaining pages were 100 - 64 = 36 pages. On the first day, Naughty had read 40% of it, which was four pages. The next day, he read page 64/4 = 14. Therefore, the number of pages left for Naughty was 36 - 14 = 22. So, in the end, Naughty finished reading 22 pages, which was four pages less than the first day.
