You need to express the sum in the same denominator. You want to find the lowest common denominator and convert each summand into its equivalent fraction having this lowest common denominator.

With denominations of 3 and of 4, LCD is 12, so you want denominator of 12.
12%2F3 is 4 so:
%287%2F3%29%284%2F4%29=28%2F12
'
12%2F4 is 3, so:
%289%2F4%29%283%2F3%29=27%2F12
'Your sum to evaluate is 28%2F12%2B27%2F12=highlight%2855%2F12=4%267%2F12%29, answered.
