Xiaofang read a story book. On the first day, she read 51 pages of the book, and on the second day, she read 10 pages. The ratio of the number of pages she had read to the number of pages she had not read was 2:3.
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.
Xiaofang read a story book. On the first day, she read 1/5 of the whole book, and on the second day, she read 10 pages. The ratio of the number of pages read to the number of pages not read was 2.
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.
Xiaofang read a storybook. On the first day, she read part of it. The ratio of the number of pages read to the number of pages unread was 2:7. On the second day, she read 42 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).
For a novel, the ratio of the number of pages that Xiaofang had read to the number of pages that she had not read was 2:5. If she read another 27 pages, it would be exactly the same as the number of pages in the novel.
If Xiaofang had already read 20 pages and the remaining pages were 5, then the total number of pages Xiaofang had read was 20 * 2 = 40 pages. If Xiaofang read another 27 pages, the total number of pages she read would be 40 + 27 = 67 pages. This novel has a total of 67 pages. Xiaofang has already read 20 pages, and the remaining pages are 47 pages.
Xiaofang was reading a storybook. The number of pages she had read before dinner was 1/7 of the number of pages she had not read. After dinner, she had read 8 more pages. This was the number of pages she had read was 1/of the number of pages she had not read...
Xiaofang read a storybook. The number of pages she had read before dinner was 1/7 of the number of pages she had not read. After dinner, she read another 8 pages. Assuming that the total number of pages in the storybook was 100. The number of pages read before dinner is 10 pages, the number of pages not read is 100 pages- 10 pages = 90 pages. After dinner, he read another 8 pages, so the number of pages he had read was 10 + 8 = 18. The ratio of the number of pages seen to the number of pages not seen was 18 pages/90 pages = 1/7. Therefore, Xiaofang had already read 7 pages before dinner, and the remaining pages were 93 pages. She read 8 pages after dinner, so she had read 93 pages + 8 pages = 101 pages in total.
Xiao Li read a book. The number of pages she had read was half of the number of pages she had not read. She read another 30 pages. At this time, the number of pages she had not read was three sevenths of the number of pages she had read. How many pages were there in this book?
This book has a total of $30+ 30> times 3/7=60$pages.
For a novel, the ratio of the pages that Xiaofang had read to the pages that she had not read was 2:5.
If she had read 20% of the pages of a novel and had not read 50%, then the number of pages that Xiaofang had read was: 20% ÷ 2 = 10% What I haven't seen is 50% divided by 5 = 10% The number of pages that Xiaofang has read is 10% + 10% = 20% Therefore, Xiaofang had already read 20% of the pages, and the remaining pages accounted for 50%.
Xiao Hong read a book. In the first week, she read 30%. In the second week, she read 55 pages. At this time, the ratio of the number of pages read to the total number of pages was 2:3.
Xiao Hong read 30% in the first week and 55 pages in the second week. The ratio of the number of pages read to the total number of pages is 2:3. We can set the total number of pages of this book as x pages. According to the question, Xiao Hong had already read 30% of the first week, which was 03x pages. In the second week, she had read 55 pages, so she had already read 03x + 55 pages. The ratio of the number of pages seen to the total number of pages is 2:3, so there is: 03x + 55 = 2/3x Solve the equation: 13x + 55 = 2/3x 13x - 2/3x = 55 01x = 55 x = 550 Therefore, the total number of pages in this book was 550.
Little Light was reading a book. The number of pages she had read was 4/5 of the number of pages she had not read. After dinner, she read another three pages. At this time, the number of pages she had read was 5:6. How many pages was this book...
Let's say the book has x pages. According to the meaning of the question, Little Light had already read 4/5 of page x, which meant that 4/5 x = 3 solved x = 3 × 5/4 = 15/2. The ratio of the number of pages that had been read was 5:6, which was 5/6 × 15/2 = 25/12. Because Little Light had read three more pages, the page ratio was 5:6, which was 25/12 = 5/8. The solution is x = 2425 because the total number of pages in the book must be an entire number, so this book has 24 pages.
Xiaofang read a story book. After a few days, the ratio of the number of pages read to the number of unread pages was 3:5. Later, she read another 27 pages.
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.
Xiaofang read an extra-cursory book. The number of pages she had read was 3.6 times that of the ones she had not read. The number of pages she had read was 52 more than the ones she had not read. How many pages were there in this book?
Let's say the book has a total of x pages and y pages. According to the meaning of the question, the number of pages seen was 36 times that of the number of pages not seen. And knowing that I've read 52 more pages than I haven't, therefore: Seen-Unseen = 52 Substituting 36:1 into the above formula, we get: 36x - x = 52 To simplify it: x = 104 Therefore, the book had a total of 104 pages.
