Exactly the same as you would do to simplify any other fraction . . .
divide top and bottom by their greatest common factor. 

The greatest common factor of  77  and  84  is  7 .
77/84

=21/84+21/84+21/84+14/84

=1/4+1/4+1/4+7/42

=3/4+7/42

=3/4+1/6

=9/12+2/12

=11/12

Or......

77÷7=11,

and 84÷7=12

Therefore 77/84=11/12.
