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.
Little Ming read a book. He read 15 pages in the first 4 days and 6 pages a day in the next 5 days. How many pages did he read on average every day?
Xiao Ming read a book for the first 4 days and read 15 pages, then read 6 pages every day for 5 days. We can use the following formula to calculate the average number of pages seen per day: Average number of pages read per day = total number of pages/days Substituting the total number of pages and the number of days into the formula, we get: Average number of pages read per day = 15 pages/4 days = 3 pages/day Therefore, Xiao Ming read an average of three pages a day.
In the first three days, he read 43 pages. In the next four days, he read 12 pages a day. How many pages did Le read on average?
Xiao Le read an average of 18 pages a day.
Wang Qiang read a book. For the first four days, he read eight pages a day, and for the next three days, he read a total of 17 pages. How many pages did he read on average every day?
Wang Qiang read a book for the first four days, eight pages a day, and then a total of 17 pages for the next three days. We can split this situation into two parts for analysis: Reading eight pages a day for the first four days meant that Wang Qiang had already read $4/times 8 = 32$pages in the first four days. Reading a total of 17 pages in the last 3 days meant that Wang Qiang had read another $3/17 = 54$page in the last 3 days. Therefore, Wang Qiang read a total of $32+54=86$pages. Next, we need to calculate how many pages he reads on average every day. Did he read all the books in the first four days and the last three days together? If that was the case, then the average number of pages he read every day was $86/4+17/3=265+5=315$pages. If not, then the average number of pages he read every day was $86/4-17/3=26-5=21$pages. Therefore, Wang Qiang read an average of 21 pages a day.
Chen Ming read a storybook and read an average of 11 pages a day for the first three days. He read an average of 18 pages a day for the next four days. How many pages did Chen Ming read on average in the past seven days?
Suppose the book has a total of x pages, and Chen Ming has read a total of y pages in these seven days: - Chen Ming read 11*3=33 pages in the first three days - In the next three days, Chen Ming read a total of 18*3=54 pages - In seven days, Chen Ming read a total of y*7=497 pages Therefore, Chen Ming read an average of 497/7=74 pages a day in the past seven days.
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 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.
He had read 12 pages on the first day, 6 more pages on the next day, and 48 pages on the last day. How many days had he read?
After reading 12 pages on the first day, he read 6 more pages every day than the previous day. On the last day, he read 48 pages. How many days did he read in total? He had read $12+12 + 12 + 12 + 12 +12+6+48$in total. Reading 6 more pages a day than the day before, so obviously in the first week, I read $12+12 + 12 + 12 + 12 +12+6+12=55$days. In the second week, he read $12+12 + 12 + 12 + 12 +12+6+12+12=63$days. By analogy, we can know that the total amount of reading before the end of the book is $55+63+70+73+80+86+98+48=695$days. Therefore, he read for a total of seven days.
If Xiaoming reads a storybook, he reads 38 pages in the first 2 days and 54 pages in the next 3 days. How many pages does Xiaoming read on average every day?
Xiao Ming read a story book and read a total of 38 pages in the first two days and 54 pages in the next three days. We can use the total number of pages to deduct the number of pages in the first two days and the next three days to get the average number of pages that Xiaoming reads every day. Total pages = 38 + 54 = 82 In the previous two days, he had read 38 pages, so the ratio of the number of pages read in the previous two days to the total number of pages was 38 pages/ 82 pages = 047875, which could be approximately expressed as 047875. In the next three days, a total of 54 pages were read. The ratio of the number of pages read in the next three days to the total number of pages was 54 pages/ 82 pages = 06667, which could be approximately expressed as 06667. Therefore, on average, Xiaoming reads 047875 × 2 + 06667 × 3 = 016533 × 2 + 023333 × 3 = 039167 × 2 + 050938 × 3 = 089715 × 2 + 010785 × 3 = 1575 × 2 + 0192 × 3 = 27533 every day, which is about 275. Therefore, Xiao Ming read an average of 275 pages a day.
Xiaoming read a book for the first four days and read an average of eight pages a day. After two days, he read a total of 48 pages. How many pages did he read per day?
Xiaoming read a book for the first four days, on average, he read eight pages a day. In the first four days, he read a total of 8 × 4 = 32 pages. In the next two days, he read a total of 48 pages, which means that in the remaining time, Xiaoming read an average of 48/7 = 8 pages per day. Therefore, Xiao Ming spent the rest of his time reading an average of 8 - 8 = 0 pages a day. In other words, Xiao Ming had already finished reading the book, so he read an average of 0 pages a day.
Xiao Ming reads a book, and after 7 days, there is still 1/3 of the book left. In the next five days, he would read 60 pages in total. How many pages did Xiao Ming read on average every day?
After reading a book for 7 days, Xiao Ming still had 1/3 of the book left. This meant that he had read 1/3 of the book and the remaining 2/3 of the book needed to read 2/3 × 7 = 4/3 days. Reading a total of 60 pages in the next 5 days meant that Xiaoming had read (60/5) = 12 pages in these 5 days. Therefore, Xiaoming read an average of 12 pages a day.
