Explanation

The working days in 2001 are 310, 300, 323, 322, and 298. The sum is 1553. The average is 1553 / 5 = 310.6, which is 310 and 3/5.

AI explanation

To find the average for the year 2001, sum the working days of all five companies: 310 + 300 + 323 + 322 + 298 = 1553. Divide this total by the number of companies, which is 5. The exact average is 1553 / 5, which can also be written as the mixed fraction 310 3/5 or the improper fraction 3103/5.
