Both are right.

To find the total number of hours worked by the 5 employees per day, we need to multiply the number of hours each employee works by the total number of employees.

First, let's convert the mixed number 6 4/15 into an improper fraction. To do this, multiply the whole number (6) by the denominator (15) and add the numerator (4) to get the new numerator:

6 * 15 + 4 = 90 + 4 = 94.

So, the mixed number 6 4/15 can be written as the improper fraction 94/15.

Now, multiply the improper fraction 94/15 by the total number of employees (5):

94/15 * 5 = (94 * 5) / 15 = 470/15.

Since the denominator is 15, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5:

470/15 = (470 ÷ 5) / (15 ÷ 5) = 94/3.

Therefore, the 5 employees work a total of 94/3 hours per day.

To convert the fraction 94/3 into a mixed number, divide the numerator (94) by the denominator (3):

94 ÷ 3 = 31 with a remainder of 1.

So, the mixed number is 31 1/3.

Therefore, the correct answer is C. 31 1/3.
