Xiaoming reads a storybook, Xiaofang reads a science book. The number of pages in a storybook is 75% of that in a science book. Xiaoming reads 15 pages a day, Xiaofang reads 18 pages a day. If Xiaoming and Xiaofang had a total of 100 pages, then they would read 100 * 15 / 100 = 15 pages a day. The remaining pages were 75% of the pages of the science book, which was 75 * 18 / 100 = 15 pages. Since the number of pages in the story book was 75% of the number of pages in the science book, the remaining pages were 75 / 75 = 1 page. Therefore, Xiaoming and Xiaofang read a total of 15 + 1 = 16 pages a day. They only read one page a day, which meant that they couldn't read the rest of the pages.
Xiaofang read 15 of the book on the first day and read 10 pages on the second day, so she read a total of ${1}{5} +{1 = 15}$pages. Assuming that the book has a total of $x$pages, then Xiaofang has read a total of $x \times \frac{1}{5} + x \times \frac{10}{1 = 10x + 50}$pages. At this time, the ratio of the number of pages read to the number of pages not read is 2, which means that the number of pages left by Xiaofang is twice the number of pages in the book, which is $x/times 2 = 10x + 50$. The solution is $x = 105$, which means that the book has 105 pages. Xiaofang read 15 pages on the first day and 10 pages on the second day. She read 25 pages in total.
Wang Xiaoming read 30 pages on the first day of reading a book. According to the plot of the novel, the first few pages would usually be read on the first day because curiosity and interest would motivate the reader to start reading as soon as possible. The 30 pages might be the beginning of the story or an important part of the plot, which was why Wang Xiaoming finished reading the 30 pages on the first day. Wang Xiaoming would probably continue to read as the story developed. If this book was a classic novel, Wang Xiaoming would probably continue reading until he finished the story.
On the first day, Xiaofang read the book's 51 pages, and the remaining pages were $51/div2 = 25$. The next day, he read another 10 pages and the remaining pages were $25 + 10 =$35. At this point, the ratio of pages seen to pages not seen is 2:3, which can be expressed as $25:35=2:3$. Therefore, Xiaofang had read the book for $2+3=5$days and still had $35-5=28$pages left.
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 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.
Xiaofang read a story book for a few days, and the ratio of the number of pages read to the number of unread pages is 3:5. Then, she read 27 pages. You can set the number of pages read as x the number of unread pages as 5x/3, so there is: x + 27 = 5x/3 The solution is x = 18 Therefore, Xiaofang had already read 18 pages, and there were 5 × 18/3 = 30 pages. She then read another 27 pages, so she had read 18 + 27 = 45 pages and still had 30 unread pages.
According to the ratio of the number of pages read to the number of pages unread on the first day was 2:7, the number of pages unread was 2/7 of the number of pages read. Because he read 42 pages the next day, the number of pages read was 42/2/7=91(pages), and the number of unread pages was 42/(2/7)=63(pages).
Xiaofang had already read three-fifths of the book, so the remaining pages were the total number: Remaining pages/total = (1 - 3/5)/total = 2/5 Therefore, the ratio of the remaining pages to the total number was 2/5:1 = 4:5.
This novel should be called " One Hundred Years of Solitude."
Xiao Dong read 3/5 of the book on the first day, which was 0.6 times the volume of the book. The next day, he read another 20 pages, which was equivalent to 1/5 of the entire book, which was 0.2 times the volume of the entire book. Therefore, the number of pages Little Dong had read was: The number of pages read = the volume of the book x the number of days read-the total number of pages = 06 × volume of the book × 1 - 02 × volume of the book = 02 × the volume of the book Since the total number of pages in the book did not change, the number of pages that Xiao Dong had read was 0.2 times that of the book.
