Answer:
-1/6
Step-by-step explanation:
A suitable calculator can evaluate this for you and show you the result as a fraction.
You start with the multiplication in the inner-most set of brackets. Here, those brackets are the absolute value function.
-2(-1/3) = +2/3
Then the sum in those brackets:
-5/6 +2/3 = -5/6 +4/6 = -1/6
The absolute value changes the sign of this back to positive, so the value in square brackets is ...
3 -(1/6) = 18/6 -1/6 = 17/6
Finally, this value is divided by -17, so you have ...
