9-5 1/3 has to be put into an improper fraction. so it would be 9/1 - 5 1/3 because 5 1/3 into a fraction would mean multiplying 5*3 and adding 1 which is 16/3. Then you have to have the same denominator so 9/1 *3 would be 27/3 and subtract 27/3 and 16/3 would get you 11/3 and simplified would be 3 2/3
