Little Ming was reading a storybook. He planned to read 12 pages a day, but he actually read 8 pages a day. In the end, he finished reading it two days earlier. How many pages is this storybook?
Xiao Ming planned to read 12 pages a day, but he actually finished reading 8 pages a day two days earlier. Assuming that this storybook has x pages: - The plan is to read x/12 days, which is x/12 pages. - Actually, x/8 days is x/8 pages. Because Little Ming finished reading it two days earlier, he only needed to read x/8 - x/12 = x/4 days. Because Xiao Ming reads 8 pages a day, he needs to read x/4 days x 8 pages = x 4/5 pages. Therefore, we can get the following equation: x/4 - x/12 = x/5 By solving this equation, one could obtain: x/12 = x/5 + 1/2 x/12 = (x+10)/5 x/12 = x/5 + 1/6 x/6 = 1/6 x = 1 Therefore, this storybook had one page.
Xiao Ming planned to read 36 pages a day, but he actually read 500 pages in 12 days. How many more pages did he actually read per day?
Xiao Ming planned to read 36 pages a day, but in fact, he read 500 pages in 12 days. 500 pages/12 days = 40 pages/day Because Xiao Ming reads 36 pages a day, the actual number of pages should be 40 pages more than the plan: 40 pages/day- 36 pages/day = 4 pages/day Therefore, Xiao Ming actually read four more pages of novels every day.
Zhang Ming read a storybook and read 30 pages a day. Three days later, there were still 58 pages left. How many pages does this storybook have?
Assuming that this storybook has a total of $x$pages: - The number of pages Zhang Ming read every day was $30. - The number of pages required to read the book in 3 days was $30,000. - The remaining page count was $58. Therefore, we can write an equation to solve this problem: $$ 30x + 58 = x $$ By solving this equation, one could obtain: $$ x = 58 - 30 = 28 $$ Therefore, this storybook had a total of 28 pages.
Xiao Ming planned to finish reading a storybook in 16 days, which was an average of 15 pages per day. Now it takes 10 days to finish reading. How many pages should I read on average every day?
Xiao Ming planned to finish reading a storybook in 16 days. On average, he would read 15 pages a day. 16 days x 15 pages/day = 280 pages Now he needed 10 days to finish the book, so how many pages did he need to read every day? Assuming that Xiao Ming can finish reading the book in 10 days, the total number of pages he needs to read every day is: 10 days x 280 pages/day = 3000 pages Therefore, Xiao Ming needed to read 3000 pages per day on average, divided by 10 days = 300 pages per day.
Zhang Ming was reading a storybook. He read 30 pages a day. After three days, there were still 8 pages of the book left. How many pages were there in this storybook?
Let's say this storybook has a total of $x$pages. According to the topic, 30 pages per day meant $30/div2 = 15$per hour. Zhang Ming read $15$pages per hour in $3$days so he read $3/30 = 90$pages in total. The remaining pages are $8/5 of the book, so there are: $$ 90 - \frac{8}{5} = \frac{16}{5} $$ Because the question requires the number of pages in the book, you need to multiply this result by $x$pages to get: $$ x \times \frac{16}{5} = \frac{16}{5} \times x = 96 $$ Solve this equation to get $x = 56$. So this story book had a total of $56$pages.
Little Ming was reading a fairy tale book. He had planned to read 12 pages a day, but he actually read eight more pages a day. In the end, he finished reading it two days earlier. How many pages does this book have?
Let's say the book has $x$pages. The original plan was to read $12$pages a day, so it would take $x$Mum $12$days to read the entire book. In fact, it would take an extra $8$a day to read the entire book, so it would take $x$Mum $12$ + $2$days. Because Xiao Ming finished the book two days earlier, he actually spent $x$Mum $12$ + $2$ - $1$days to finish the book. We can solve this problem by using the exponential sequence sum formula: $$x \div 12 + 2 - 1 = \frac{x \times (12+2)}{12}$$ The solution is $x=300$. Therefore, the book had a total of $300$pages.
A storybook had 250 pages, and Xiao Ming read 15 pages a day. Could he finish it in two weeks?
Wang Ying was reading a 336-page storybook. He planned to read 24 pages a day. How many days would it take for him to finish reading?
Wang Ying was reading a 336-page storybook. He planned to read 24 pages a day. The number of days needed to finish reading this book was: 336 pages/24 pages/day = 15(days) Therefore, Wang Ying needed 15 days to finish reading the 336-page storybook.
Little Light read a storybook and read 60 pages a day. After three days, he still had 5/8 of the book left. How many pages was this storybook?
Let's say this storybook has a total of $x$pages. Reading $60$pages a day, the number of pages Little Light read in $3$days was: $$60\times3=180$$ The remaining pages are 5/8 of the book, so the following equation can be written: $$x\div5=8\times60\times3$$ Solve this equation: $$x=2400$$ So this storybook had a total of $2400 pages.
A storybook has 200 pages. Xiao Ming read two-fifths of it on the first day and 15% on the second day. How many pages are left?
Xiao Ming read two-fifths of the page on the first day. The next day, he read 15%, which was page 015. Therefore, the remaining pages were 200 - (2/5 + 015) = 200 - 045 = 19545 pages. Therefore, Little Ming still had 19545 pages left.
Xiao Ming read a 480-page storybook and read page A every day for 12 days. How many pages are left?
When Xiao Ming read page A of the storybook every day for 12 days, he had read a total of 12 × page A. Therefore, when Xiaoming reads a 480-page storybook, he still has 480 - 12 × a pages left. To calculate the remaining pages, he needed to know how many pages Xiao Ming read in the end and how many pages he read every day. If we assume that the last page that Xiao Ming read was 480 pages and he reads page a every day, then we can write the following equation: 480 - 12 × a = Remaining pages By solving this equation, we can get: Remaining pages = 480 - 12 × a = 480 - 12a Therefore, after reading page A for 12 days, Xiao Ming still had 480 - 12A pages left.
