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.

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.

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 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.
