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%.
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).
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 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 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.
A storybook had 56 pages, and Xiaofang had read seven times the number of pages left. How many pages has Xiaofang read?
The total number of pages that Xiaofang had read was 56. The remaining pages were 56-1=55 pages. The number of pages that Xiaofang had read was 55×7=355 pages.
Xiaofang has read a book and has read 3/5 of the book. What is the ratio of the remaining pages to the total number?
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.
Xiaoming read a story book, Xiaofang read a science book. The number of pages in a story book was 75% of that in a science book. Xiaoming read 15 pages a day, Xiaofang read 18 pages a day...
Xiaofang was reading a storybook. Before dinner, the number of pages she had read was 1/7 of the unread pages. After dinner, she read another 8 pages. At this time, the number of pages she had read was 1/7 of the unread pages...
Xiaofang was reading a storybook. The number of pages she had read before dinner was 1/7 of the unread pages. After dinner, she read another 8 pages. At this time, the number of pages she had read was 1/7 + 8 = 19/7. Therefore, Xiaofang read 1/7 pages before dinner and 19/7 pages after dinner. 19 + 1/7 + 1/7 = 46/7 pages. Answer: Xiaofang read 1/7 pages before dinner, 19/7 pages after dinner, 46/7 pages in total.
Xiaofang has read 80 pages of a science book, and there are still 31 pages left. What she has read accounts for a few of the total pages of the book
The total number of pages in this book was 80 + 31 = 111. Therefore, the number of pages that Xiaofang had read accounted for the total number of pages in this book: 111 pages = 1 / 11 In other words, the number of pages that Xiaofang had read accounted for 1/11 of the total number of pages in the book.
