Xiao Hong read a book with 95 pages for five days. Xiao Li read this book with 30 pages a day. On average, how many pages did Xiao Hong read less than Xiao Li every day?
Xiao Hong spent a total of five days reading this book and had read a total of 95 pages. Xiaoli read 30 pages a day for a total of 5 days, so Xiaoli read a total of 30 × 5 = 150 pages. Then how many pages does Xiao Hong read less than Xiao Li on average every day? The total number of pages that Xiao Hong read was 95. The total number of pages that she read every day was 95/5 = 19. The total number of pages Xiao Li read was 30 x 5 = 150 pages. The total number of pages she read every day was 30 pages. This was because Xiao Hong read 19 - 30 = -1 pages less than Xiao Li every day. Therefore, Xiao Hong read an average of 19 pages less than Xiao Li every day.
Xiao Hong read 170 pages in 12 days, Xiao Ming read 240 pages in 17 days, Xiao Qiang read 27 or 28 pages, 300 pages. Who can read fast?
According to the knowledge of online literature enthusiasts, it was difficult to come up with a conclusion as to who read faster because everyone's progress was different at different times. Xiao Hong only reads 170 pages a day while Xiao Ming only reads 240 pages a day, which means that Xiao Hong is reading faster than Xiao Ming. However, Little Red only had 12 days while Little Ming had 17 days. Therefore, Little Ming had a longer reading time and progress. In addition, Cockroach read 300 pages between the ages of 27 and 8, which means that his speed may be faster than Xiao Hong and Xiao Ming. Therefore, it was impossible to simply answer the question of who read faster.
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.
Xiao Hong read a book and read 15 pages a day. After 4 days, she read three-fifths of the book. How many pages does this book have?
Assuming that the book has a total of $x$pages, how many pages has Xiaohong read in 4 days? Based on the 15 pages she read every day, she read a total of $15,4 =$60 pages. Then she read three-fifths of the book, which means that she only read the $3/5 part of the book. Therefore, we can write the equation: $$60 = 3/5 \times x$$ To solve this equation, you can get $x = 60 times 5/3 = 100$. Therefore, the book had a total of 100 pages.
Xiao Jun read a book and read two-thirds of the book in seven days. In the next five days, he read a total of 40 pages and just finished it. How many pages are there in this book?
Suppose the book has x pages: Seven days ago, Xiao Jun read 7 × 2/3 = 14/3 pages, which was 14/3 div7 = 4/9 pages. Xiao Jun read (x + 5) × 4/5 = x + 20/3 pages in the last 5 days. Because Xiao Jun had read a total of 40 pages, there were: 4/9 + 20/3 = x The solution was x = 360/9 + 20/3 = 480/3 pages. Therefore, this book had a total of 480/3 pages.
Question: Xiao Hong borrowed a book. After reading it for five days, there were still 12 pages left. Xiao Hong had to return the book in three days. How many pages did she read on average every day?
Xiao Hong borrowed a book and read it for 5 days. There were still 12 pages left, so she had read a total of $5+12=17$pages. Little Red had to return the book in 3 days, so the number of pages she needed to return was $17+3=20$pages. We can calculate the average number of pages of the remaining pages per day using the following formula: $$ Remaining pages = total pages-number of pages already seen $$ Since Little Red had already read 17 pages, the remaining pages should be $17- 17> times 2=0$per day. Therefore, Little Red had to read an average of 0 pages a day.
Xiao Xiao read a book. She read 20 pages a day. After 5 days, she still had 60% of the book left. How many pages is this book?
Assuming that this book has $n$pages and Xiaoxiao reads $20$pages a day, then she reads a total of $/frac{20/times 5}=50$pages. The rest of the books have a total of $n-50$pages, where $/frac{60}{n}$represents the proportion of the number of pages in the book. If the ratio is simplified to $\frac{60}{n}=\frac{n-50}{n}\times 100$, then $n=1200$. So this book is $1200$pages.
Xiao Hong read a book and read 15 pages a day. After two days, there was still 60% of the book that she had not read. How many pages was this book? Ask for detailed steps
Little Red read 15 pages a day and had read 60% of the book in two days. Therefore, there were still 60%/15 = 4 pages left. The remaining four pages were read by Little Red every day for the remaining six days. Therefore, if you read one page a day, you can finish the remaining four pages in four days. 4 × 1 = 4(pages) Therefore, this book had a total of four pages.
Xiao Ming reads a book, and after 7 days, there is still 1/3 of the book left. In the next five days, he would read 60 pages in total. How many pages did Xiao Ming read on average every day?
After reading a book for 7 days, Xiao Ming still had 1/3 of the book left. This meant that he had read 1/3 of the book and the remaining 2/3 of the book needed to read 2/3 × 7 = 4/3 days. Reading a total of 60 pages in the next 5 days meant that Xiaoming had read (60/5) = 12 pages in these 5 days. Therefore, Xiaoming read an average of 12 pages a day.
Xiao Hong read a book and read 15 pages a day. After four days, she still had three-fifths of the book left. How many pages was this book?
Let's say the book has $x$pages. Reading 15 pages a day, it would take Xiaohong $x$days to finish reading this book. The remaining pages were three-fifths of the book, which was $025x$. According to the question, it would take Xiaohong four days to finish reading this book. Therefore, we can write the equation: $$ x + 025x = 025 \times (x+4) $$ Solve this equation: $$ x = 30 $$ So this book has 30 pages.
Xiao Xiao read a science book on the first day and read 30 pages, which is two-fifths of the book. How many pages has Xiao Xiao not read yet?
Your question is a little unclear. Can you provide more context information? For example, what is the "book" that you are referring to and why did Xiaoxiao read it? This way, I can better help you answer your questions.
