OK, T, we have to subtract 3/4 from 11/12
 
If we let the distance he still has to go be D then
 
D = (11/12 mile) - (3/4 mile)
 
In order to do this, we have to convert (3/4) to a fraction whose denominator is 12.
 
(3/4 mile)*(3/3) = (9/12 mile)
 
So D =(11/12 mile) - (9/12 mile) = (2/12 mile) or (1/6 mile)
Hi T;
Sorry, I misread the question.  William is correct.
(11/12)-(3/4)
(11/12)-[(3/4)(3/3)]
(11/12)-(9/12)=2/12=1/6
