Mrs. Henson, of the Antique Attic, can polish 11 antique chairs in 3 hours. Find Mrs. Henson's rate per hour. (write your answer as a fraction.)

11/3 or 3 2/3.

You can find the rate by dividing 11 by 3, or making the fraction 11/3.

11/3 cannot be simplified further because the numerator and denominator are both prime numbers, so they can't be divided by any whole number to get another whole number.
