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.
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.
Lili read a storybook. She read 78 pages in the first 3 days and 40 pages a day in the next 4 days. how much of this book
Assuming the book has a total of n pages, Lili read 78 pages in the first 3 days, then there are still n - 3 × 78 = n - 262 pages not read. In the next four days, she read an average of 40 pages a day. In these four days, Lili read a total of 40 × 4 = 160 pages. Therefore, Lili had read a total of n - 262 + 160 = 322 pages, just enough to finish the book. So this book had 322 pages.
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.
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.
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.
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.
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.
Lili finished reading a storybook in 8 days. She read 150 pages in the first 3 days. For the next 5 days, I read 42 pages a day. How many pages do I read on average every day?
Lili spent 8 days to finish reading a storybook. She read 150 pages in the first 3 days and 42 pages a day in the next 5 days. So she read a total of $150/times 3 + 42/times 5 = 2220$pages. And the total time she spent was $8$days, so she read an average of $2220 / 8 = 265$pages per day. So Lili read an average of 265 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.
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.
