Your answer would be 3/4 (three quarters).

This can be simplified even further because both the numerator (6) and the denominator (8) can be divided by 2.
So-- 6 divided by 2 would be 3, and 8 divided by 2 would be 4. 3/4 cannot be simplified even further so this would be your final answer.
I hope this helped you out a bit :]
