Xiao Ming read an average of 15 pages a day. He had already read 4 pages, so he still needed to read 4/15 = 02 days. Because Xiao Ming needed to watch for 5 consecutive days, he could move the days that he needed to watch forward by 5 days. 2 days + 4 days = 6 days Therefore, Little Ming needed to start from page 6, which was page 11.

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 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 Ming read a novel on the first day and read 1/8 of the entire book with 21 pages more. On the second day, he read 1/6 of the entire book with 4 pages less, leaving 102 pages unread. We can use the following formula to calculate the remaining pages: Remaining pages = total pages-number of pages viewed Putting the known information into the formula, he obtained: Remaining pages = 102 pages Therefore, Xiao Ming read 1/6 of the book on the second day, leaving 102 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 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.

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 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.

How many days has Xiaoming been watching? (Question symbol) I've been reading for seven days, so I haven't read seven pages. The remaining pages were 256 - 13 × 7 = 234 pages. Therefore, Little Ming still had 234 pages to read.

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.
