Xiao Ming read a book and read 15 pages a day. After reading for 4 days, he still had 2/5 of the book left. How many pages does this book have?
Xiao Ming read a total of $4/15 = 60$pages in 4 days. The remaining pages are $2/5$of the book, so the book has a total of $2/5/60 = 48$. Thus, the book had a total of 48 pages.
Xiao Ming read a book. He read 24 pages a day. After 3 days, he still hadn't read 9% of the book. How many pages did this book have?
Xiao Ming reads 24 pages a day and after 3 days, there are still 9/11 pages left. Remaining pages = book pages × 911/11 Substituting the number of pages in the book into the above formula: Remaining pages = 729 pages/11 Since Xiao Ming reads 24 pages a day, 24 × 3 = 72 pages of the remaining pages have already been read by Xiao Ming. Number of pages in the book-number of pages viewed = number of pages remaining That is: 729 pages- 72 = 720 pages Thus, the book had a total of 720 pages.
Xiao Ming read a book. He read 72 pages in the first 4 days and 29 pages a day for the next 6 days. How many pages did he read on average every day?
If Xiaoming reads 72 pages in the first 4 days, then Xiaoming's total page count in the first 4 days is 72 pages. Reading 29 pages every day for the next 6 days would mean that the total number of pages for the next 6 days would be 29 pages x 6 days = 171 pages. Therefore, Little Ming's total page count in the last six days was 171 pages. Little Ming read 171 pages per day for the next 6 days, 6 days = 27 pages. Therefore, Xiao Ming read an average of 27 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 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 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 Dong read a book and read 24 pages a day. After 6 days, there were still 3/5 of the book that he had not read. How many pages was this book?
Assuming that the total number of pages in this book is X, then according to the information given in the title, the following equation can be written: Xiao Dong reads 24 pages a day, so he reads a total of $24/times 3 = 72$pages After 6 days, there are still 3/5 of the book left, so there are still $X <br><br><br> By equating the two equations in the system of equations, one could obtain: $$24 \times 3 = \frac{X}{5}$$ Solution: $$X = 72 \times 5 = 360$$ Therefore, the total number of pages in this book was 360.
Xiao Ming reads a book 20 pages a day, after three days, he still has five-eighths of the book to read.
The number of pages in this book is 256. Xiaoming reads 20 pages a day, so he can read 24 pages a day. In three days, he could finish reading a book with 256 pages. Therefore, Xiao Ming read a total of 256 pages x 3 = 768 pages in three days. After reading these 768 pages, Little Ming still had 768 pages- 256 pages = 512 pages to read. Little Ming read 512 pages/ 20 pages = 26 days. Therefore, this book had a total of 256 + 512 = 768 pages.
Xiao Ming is reading a book. He had read 20% of the total number of pages on the first day. The number of pages read on the second day was 5:4 compared to the number of pages read on the first day. There were still 110 pages left to be read…
Xiao Ming reads a book on the first day, 20% of the total number of pages, and the number of pages read on the second day is 5/4 of the number of pages read on the first day, leaving 110 pages Assuming that the total number of pages in this book is x: I read 20% on the first day, which is 02x pages. I read 5/4x pages the next day because I read more pages the next day than the first day The remaining pages are x -02x- 5/4x = 110 pages Solve the equation: x = 1100 Therefore, the total number of pages in this book is 1100. Xiaoming read 200 pages on the first day and 300 pages on the second day.
Xiao Ya was reading a 114-page book. On average, he read 12 pages a day. After reading for a few days, there were still 18 pages left?
Ya-chan reads a 114-page book, on average, 12 pages a day. After a few days, there are still 18 pages left. You can calculate it by the following steps: 114 pages/12 pages/day = 9 days Since Ya-chan needed 9 days to finish reading the book, he needed to read it from the 1st day to the 9th day, a total of 9 days. In these nine days, Ya-chan needed to read 12 pages a day, so in total, he would read: 12 pages/day x 9 days = 108 pages However, there were still 18 pages left, so Ya-chan had to read the remaining 18 pages every day: 18 pages/day = 1 page In other words, Ya-chan needed to read an extra page of the remaining 18 pages every day to finish the book.
Xiao Hua read a book and read 15 pages a day. After reading for 4 days, he still had 2/5 of the book left. How many pages of this storybook had he not read?
Assuming that this storybook had $x$pages, then the number of pages Little Light read every day was $15/div4 = 375$pages. Little Light had already read $4$for days, so the remaining pages were $x - 4/375 = x - 1125$. Because the number of pages Little Light reads every day is fixed, the number of pages can be expressed as: $$x - 4 \times 375 = 375 \times 4 - 1125$$ The above formula was simplified to: $$x = 48$$ Therefore, there were still $48 - 1125 = 3675 pages of this storybook that he had not read.
