Xiao Hong had read a book. In the first week, she had read 30% of the entire book, which was more than eight pages. At this time, there were still 76 pages that she had not read. How many pages was this book?
In the first week, Xiao Hong read 30% of the entire book, which was more than 8 pages. In other words, Xiao Hong read 8 + 30% + 8 = 13 pages. The remaining pages are 76, so the number of pages in the book is: 76 ÷ (1 - 30% - 8) = 76 ÷ 07 = 110 So this book has 110 pages.
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.
Xiao Hong had read a book. She read 24 pages a day. After five days, she still had 40% of the book left. How many pages was this book?
Little Red read 24 pages a day for 5 days, so how many pages did she read in total: 5 days x 24 pages/day = 120 pages The rest of the book takes up 40% of the whole book, so the remaining pages take up: 40% ÷ 100% = 04 The pages of the book were: 120 pages/04 = 300 pages So this book has 300 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.
A book had a total of 95 pages. Xiao Hong read 13 pages a day. Could she finish it in a week?
No. He read 13 pages a day for a total of seven days a week. Therefore, Little Red needed 7 * 13 = 91 pages to complete the reading mission for a week. However, a book has a total of 95 pages, so Little Red needs to read 91 pages.
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. 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 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.
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 does this book have?
Suppose the book has x pages. According to the question, the number of pages seen was 36 times that of the number of pages not seen. The number of pages seen: the number of pages not seen = 36:1. It is also known that there are 52 more pages that have been read than those that have not been read, so there are: Number of pages seen + 52 = Number of pages not seen To simplify it: 36x + 52 = 1x Solve the equation: 06x = 52 x = 80 Therefore, the book had a total of 80 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.
Ding had read 300 pages of a book, which was 27 pages less than the number of pages he had not read. How many pages were left?
Assuming that the book has a total of n pages, then the ones that Ding has not read are n-300 pages. According to the question, Ding read 300 pages more than he did not. n - (n-300) = 300 To simplify it: 2n - 300 = 300 2n = 300 + 300 2n = 600 n = 300 Therefore, the book had a total of 300 pages. Little Ding had already read 300 pages, but he hadn't read 300-300=0 pages. Hence, there were still 0 pages left.
