When Little Red was reading a book, 5/7 of the pages she had read was equal to 3/5 of the pages she had not read. Little Red had already read 210 pages. How many pages were left?
According to the description of the question, 5/7 of the pages that Little Red had read was equivalent to 3/5 of the pages that she had not read. The number of pages Little Red has read = the number of pages she has not read x 5/7 = 210 pages x 3/5 = 350 pages Therefore, Little Red had 210 pages- 350 pages = 80 pages left. Therefore, Little Red still had 80 pages to read.
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 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.
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.
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.
When Little Min read a storybook, the ratio of the number of pages that she had read to the number of pages that she had not read was 3:5. If the entire book had 200 pages, how many pages were left unread?
Little Min had already read 30 pages and there were still 50 pages left.
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, she had read 1/6 of the unread pages. This book...
How many pages are there in this storybook? Xiaofang had read 1/7 of page before dinner and 8 pages after dinner, so she had read 1/7 + 8 pages, which was 11/7 pages. Then this storybook had a total of (11/7) + 1 = 18/7 pages.
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.
Xiao Lan was reading a storybook. The number of pages she had read before dinner was 1/5 of the number of pages she had not read. After dinner, she had read another 6 pages, which was 1/4 of the number of pages she had read.
Xiaolan read a story book. The number of pages she had read before dinner was 1/5 of the number of pages she had not read. After dinner, she had read 6 pages. This was 1/4 of the number of pages she had read. Then, what was the number of pages she had not read? The number of unread pages is the number of pages in the entire story minus the number of read pages. Therefore, the number of pages that Xiaolan had read before dinner was 1/5 of the number of pages that she had not read. Number of pages seen = number of pages not seen × 5/4 He also knew that Xiaolan had read six pages after dinner, so he said," Number of pages seen = Number of pages seen + 6 = (Number of pages not seen × 5/4) + 6 (Add 6 to both sides of the equation) The equation was simplified to: Number of pages viewed = 26 × 5/4 + 6 = 36 + 6 = 42 Therefore, Xiaolan had read page 42 before dinner, but she hadn't read page 42-36=6.
Little Red read a book and read 15 pages a day. After four days, she still had 3/5 of the book left. How many pages was this book?
Little Red reads a book 15 pages a day, and after 4 days, there is still 3/5 of the book left. We can assume that this book has x pages. According to the question, Little Red had read a total of $4/times 15 = 60$pages in 4 days. The remaining pages are 3/5 of the book, so there are: $$ 60\div 3/5=24 $$ Therefore, the book had 24 pages.
Little Red read a book and read 15 pages a day. After four days, she still had 3/5 of the book left. How many pages was this book?
Assuming that the book has a total of $x$pages, then Little Red has read $x/times 15$pages in 4 days. The remaining pages are 3/5 of the book's worth, so there are: $$x <times 15><times 3/5>= Total pages $$ Solve this equation: $$x = \frac{total pages}{15} = \frac{1200}{15} = 80$$ Therefore, the book had a total of 80 pages.
