Xiaohong borrowed a book from the library. Time is money, with a total of 132 pages. After reading for five days, there are still 72 pages left. On average, she reads a little more every day.
A * * * The number of pages read is 132-72=60 (pages), and the average number of pages read every day is 60÷5= 12 (pages).
If you want to calculate how many days it takes to finish reading, it is 72÷5= 14.4, but the number of days has no decimal, it should be 15 days, and cannot be rounded off.
