If Xiao Ming read 35 pages a day, he would finish the book one day later than the stipulated date. If he read 40 pages a day, he would have to read 5 pages less on the last day.Xiaoming reads a novel. If he reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day.
Based on this information, we can formulate the following equation:
Let the total number of pages in the novel be x Xiaoming reads x/35 days, that is, he reads x/35 pages every day.
Because Xiao Ming needed to finish reading the entire book, he needed to meet the following two conditions:
Xiaoming finished reading the novel before the stipulated date
2 Xiao Ming reads 35 pages a day, so the total number of pages read is 35x/12 days
Therefore, we can write the following equation:
x/35 = (x/12) - 1
Solve the equation:
x = 35x/12 + 1 = 40
Therefore, Xiao Ming needed to read 40 pages to finish the novel. He needed to read 40/35=8/17 days before the specified date. However, because reading 40 pages a day is slower than reading 35 pages, the actual time he needs will be longer than 8/17 days, that is, he will need 16/17 days to finish reading the novel.
Xiao Ming borrowed a 500-page novel and read 280 pages in the first 5 days. How many pages did he read on average every day?Xiao Ming had read 280 pages in the past 5 days, so he had already read 280 x 5 = 1400 pages.
The book has 500 pages, so the remaining pages are 500 - 1400 = -700 pages.
This means that Xiaoming has to reread the 700 pages of the book in the next 7 days, but he can choose to start reading on any day.
If Xiao Ming chose to start reading from the sixth day, then the number of pages he needed to read every day was 700/6 = 100 pages.
Therefore, Xiao Ming needed to read 100 pages on average every day.
Xiao Ming read a book. On the first day, he read 10% of the book, the second day, he read 35%, and the third day, he read 44 pages. This book…How many pages are there in this book?
According to the title, Xiaoming read 10% of the book on the first day, which was 10% of the book divided by 100% = 1/10 pages.
Xiao Ming read 35% of the book the next day, which was 35% of the book divided by 100% = 035 pages.
Xiao Ming read 44 pages of the book on the third day, so the number of pages in the book can be calculated by the following formula:
1 ÷ (1/10 + 035 + 1/10) = 44
Solve the equation:
Number of pages in the book = 44 × 100%/(1 + 035 + 1) = 3520
Therefore, this book had a total of 3520 pages.
A storybook had 250 pages, and Xiao Ming read 15 pages a day. Could he finish it in two weeks?A 250-page storybook could be finished in two weeks if Xiaoming read 15 pages a day.
The calculation process was as follows:
First week:
In the first week, Xiaoming needed to read 6 days to finish 15 pages/day * 6 days = 90 pages.
Second week:
Little Ming needed to spend another 5 days to finish reading the remaining 90 pages of the storybook.
The total time required is:2 weeks * 2 = 4 weeks
Therefore, Xiaoming needed four weeks to finish reading a 250-page storybook.
Xiao Ming read a book. On the first day, he read 1/6 of the book, the second day, he read 24 pages, and the third day, he read the total number of pages in the previous two days.Xiao Ming read a book on the first day, he read 1/6 of the whole book, the second day, he read 24 pages, the third day, he read the total number of pages in the previous two days
If he read 24 pages the next day, he would read (24 div6) = 4 pages the next day.
The rest of the books had 5/6 pages. Xiaoming read 1/6 pages on the first day, so he read (5/6 div1/6) = 30 pages on the first day.
Xiao Ming's remaining book had 1/6 pages. The number of pages he read the next day was 4 + 30 = 34.
Xiao Ming's remaining book had 1/6 pages. The number of pages he read on the third day was 34 + 24 = 58.
Therefore, on the third day, Xiao Ming read the entire book's 58 + 6 = 9 pages.
