Answer: 3 1/6
Explanation:
-1 1/3 would be converted into an improper fraction which is -4/3.
-4 1/2 in an improper fraction is -9/2 but you need to get the same denominators.
You change -4/3 to -8/6, and -9/2 to -27/6
You then do -8/6 - (-27/6) so you are actually adding cause of the two negative signs!
You should get 19/6 which is 3 1/6 in mixed form.
