Xiao Gang reads a story book every day and reads 56 pages. After reading for four days, there are still 3/11 pages left. How many pages is this book?
Let's say the book has $x$pages. Xiao Gang reads $56$pages a day, so the number of pages needed to finish the book in four days is $56/times 4 = 216$pages. The remaining pages are $3/11$of the book, which means that the remaining pages are $216/div3/11 = 80$pages. Because Xiao Gang still needed to read for four days, the total number of pages he needed to read was $80 + 4 = 84$pages. Therefore, the book has a total of $x = 84$pages.
Xiao Ming reads a novel, if he reads 35 pages a day,
If Xiao Ming reads 35 pages a day, then his reading speed is very fast. According to some studies, the average human can read about 200-300 pages a day, and some professional readers may read more. If Xiao Ming's reading speed could reach this level, he might gain more understanding and experience in the novel.
Xiao Ming reads a book, if you read 35 pages a day
According to the information provided, if Xiaoming read 35 pages a day, he would need eight days to finish reading. The book had a total of 315 pages, so he needed to read 39 pages a day to finish it by date. On the last day, he needed to read 42 pages to finish reading.

Xiao Xin reads a book, reads 12 pages a day, and after 5 days, there is still 40% of the book left. How many pages is this book?
Assuming the book has a total of $x$pages: - How many days did Xiao Xin read the $12$page every day? - Xiao Xin has read $5$for days and has $40 $left. This means that there are still $(40/100)/times 12$pages left. - This book has a total of $x$pages, so there are: $$ 12\times 5 + (40/100)\times 12 = x $$ Solve the equation: $$ x = 80 $$ So the book had a total of $80$pages.
Xiao Hong reads a book and reads 15 pages a day. After 4 days, there are still four-fifths of the book that she hasn't read. How many pages is this book?
Let's say the book has $x$pages. Reading 15 pages a day meant that you could read $4/times 15 = 60$pages in 4 days. The rest of the content that he did not read was four-fifths of the book, which was $x/div4 = 5x/4$. Solve the equation to get $x = 40$. So this book has 40 pages.
Xiao Ming reads a book. If he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads 15 pages a day, the total number of pages he needs is: 15 pages/day x 24 days = 360 pages Therefore, Xiao Ming needed to read 360 pages to finish it in 24 days. The number of days required to read 20 pages a day is: 20 pages/day x days = 20 days Therefore, Xiao Ming needed to read for 20 days to finish the book.
Xiao Ming reads a book. He reads 1/13 of the book every day. After 4 days, there are 90 pages left. How many pages are there in this book?
Assuming that the book has $x$pages, the number of pages that Xiaoming reads on the fourth day is $x$multiplied by $1/13$. Because Xiao Ming had read for 4 days, the number of pages he read plus the remaining pages equals the total number of pages: $$ x + (x \times 1/13) + 90 = x $$ To simplify it: $$ x \times 12 - x \times 1/13 + 90 = 0 $$ Solve this equation: $$ x = 130 $$ Therefore, the book had a total of 130 pages.
Xiao Ming reads a book, reads 15 pages a day, and after 4 days, there are still 3/5 of the book left unread. How many pages is this book?
Assuming that this book has $n$pages, Xiaoming reads $x$pages every day: $$ 4\times 15 = 3/5 \times n $$ The solution is $n = 50$. So this book has 50 pages.
The number of pages that Xiaoming reads on the first day is 20% of the whole book. The next day, he reads 20% of the remaining pages. The number of pages that he reads on the second day accounts for 100% of the total pages of the whole book.
The number of pages that Xiaoming reads on the first day is 20% of the whole book. The number of pages that he reads on the second day is 20% of the remaining pages. The percentage of the number of pages that he reads on the second day can be calculated as follows: The number of pages that Xiaoming read on the first day was 20% of the entire book. In other words, the total number of pages that Xiaoming read was: Total pages = 20% × pages of the book = 02 × pages of the book The number of pages that Xiao Ming read the next day was 20% of the remaining pages. In other words, the total number of pages that Xiao Ming read was: Total pages = 20% x Remaining pages = 02 x Remaining pages Then, the percentage of the number of pages that Xiao Ming read the next day in the total number of pages in the book can be calculated as: The number of pages Xiao Ming read the next day divided by the total number of pages in the book × 100% = 02 divided by 08 × 100%= 25% Therefore, the number of pages that Xiao Ming read the next day accounted for about 25% of the total number of pages in the entire book.
Xiao Ming reads a book, reads 16 pages a day, and after 5 days, there are still 3/5 of the book left unread. How many pages does this book have?
Assuming the book has $x$pages: - Xiao Ming read $5$days and read $16$pages every day, so he read $5/times 16 = 80$pages. - The remaining pages are 3/5 of the book's worth, so there are: $$ x - 5 \times 16 = 3/5 \times x $$ The above formula was simplified to: $$ x = 320 $$ So this book is $320$pages.
