Answer:

9 1/12

Explanation:

3 1/3 + 5 3/4

Get a common denominator of 12

3 1/3*4/4 + 5 3/4 *3/3

3 4/12 + 5 9/12

8 13/12

8 + 12/12 + 1/12

8+1+1/12

9+1/12

9 1/12

Changing to improper fraction

3 1/3 = ( 3*3+1)/3 =10/3

5 3/4 = ( 4*5+3)/5 =23/4

Getting a common denominator

10/3 * 4/4 = 40/12

23/4 *3/3 =69/12

-------------

109/12

12 goes into 109 9 times

9*12 = 108 and that leaves 1 left over

9 1/12
