A book had a total of d pages. Xiao Dong read e pages every day. After reading for f days, there were still 2 pages left. Xiao Dong read a few pages. You can still think he's watching
According to the description of the question, Xiao Dong read page e every day. After reading for f days, he had read e × f = d + 2 pages. Therefore, Xiao Dong still needed to look at the d-e × f page, which meant that Xiao Dong also needed to look at the (d-e) × f page. Since Xiao Dong had already read page d, plus the content he still needed to read, the total was e × f + (d-e) × f pages. Therefore, Xiao Dong had already read d + 2 pages and still needed to read (d-e) × f pages. In summary, Xiao Dong had read page d + 2 and needed to read page (d-e) × f.
Xiao Dong read a 420-page book. He read 26 pages a day. After reading for 13 days, how many pages were left?
A book has a total of 150 pages, and Xiao Ming has already read 54 pages. The remaining pages are 8 pages a day, and it will take him a few days to finish them.
Xiao Ming had already read 54 pages and was reading 8 pages a day. Therefore, he still needed 8 × 7 = 56 days to finish reading the remaining pages.
Xiao Dong read a storybook. He read 68 pages in the first four days and 72 pages in the next three days. How many pages does Xiao Dong read on average every day?
Assuming that the total number of pages Xiao Dong read every day was constant, then the average number of pages he read every day could be calculated by calculating the total number of pages in the first 4 days and the last 3 days. The total number of pages read in the first four days was 68, so Xiao Dong had read a total of 68 pages in these four days. The total number of pages he read in the next three days was 72 pages, so Xiao Dong read a total of 72 pages in these three days. Therefore, Xiao Dong had read a total of 68 + 72 + 10 + 2 = 190 pages in these 8 days. Divide the total number of pages by the total number of pages you read every day to get the answer to how many pages Xiao Dong reads on average every day: 190/8 = 225 pages The answer was 225 pages because Xiao Dong read an average of 225 pages a day.
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.
A book has a total of 90 pages. After reading for 2 days, there are still 30 pages left. How many pages does Xiaohua read every day?
A book has a total of 90 pages. After reading it for two days, Little Light still has 30 pages left. 30 pages/2 days = 15 pages/day Because Little Light reads 15 pages of this book every day, the proportion of pages that Little Light reads every day is: 15/90 = 1/6 Therefore, Little Light read one-sixth of the book every day.
Xiaoming reads a book on the first day, reading 20% of the total number of pages, the number of pages read on the second day and the number of pages read on the first day is 5:4
Xiao Ming read 20% of the total number of pages on the first day of reading a book, which means that the total number of pages multiplied by 20% equals 20% of the total number of pages. On the second day, the ratio of pages read on the first day was 5:4, which meant that half of the total pages read on the second day was 25% of the total pages. Therefore, Xiao Ming read the total number of pages multiplied by 25% the next day, which was equal to the total number of pages multiplied by 5%. Divide the total number of pages by 5 to get the number of pages that Xiaoming read the next day divided by 5. That is, the total number of pages divided by 5 multiplied by 40% equals the total number of pages multiplied by 10%. Therefore, Xiao Ming read the total number of pages multiplied by 10% the next day, which was equal to the total number of pages multiplied by 5.
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 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.
A book had a total of 95 pages. Xiao Hong read 13 pages a day. Could she finish it in a week?
Dong Dong spent a week reading a storybook. He read 150 pages in the first three days and 200 pages in the last four days. How many pages did Dong Dong read on average every day?
Dong Dong spent a week reading a storybook. He read 150 pages in the first three days and 200 pages in the next four days. We can use the formula of "A total of X pages in the previous N days, an average of Y pages per day" to calculate how many pages Dongdong reads on average per day: 1 Calculating the total number of pages in the first three days:150 pages/3 days = 50 pages/day 2. Total pages in the next four days:200 pages/4 days = 50 pages/day 3. Calculating the average number of pages per day: Total pages/days = 50 pages/day/7 days = 75 pages/day Therefore, Dongdong read an average of 75 pages a day.
