Convert each mixed number to improper fraction form
3 & 1/3 = 3 + 1/3
3 & 1/3 = 9/3 + 1/3
3 & 1/3 = 10/3
5 & 1/2 = 5 + 1/2
5 & 1/2 = 10/2 + 1/2
5 & 1/2 = 11/2
------------------------
Then use those two improper fractions to divide. You take the reciprocal of the second fraction and then multiply.
(3 & 1/3) divided by (5 & 1/2) = (10/3) divided by (11/2)
(3 & 1/3) divided by (5 & 1/2) = (10/3) * (2/11)
(3 & 1/3) divided by (5 & 1/2) = (10*2)/(3*11)
(3 & 1/3) divided by (5 & 1/2) = 20/33
-------------------------
Answer: 20/33
