first you'd have to make 8 a fraction so it would be 8/1 then you need a common denominator so you multiply 8 and 1 by 6
8 times 6 = 48
1 times 6 = 6
then you subtract 11 from 48 = the answer is 37/6
48-11= 37 so then it is 37/6 do not simplify if it says not to but if you were to simplify you would divide 37 by 6 and get 6 with 1 remaining so the answer would be 6 1/6
I hope this helps!
