There must be more to this than meets the eye--i.e. more parentheses needed to dictate proper order of operations--or this would be easily simplifiable.
So you ought to edit it and make sure that all denominators and numerators are enclosed in their own parentheses, to follow PEMDAS rules properly. Remember that this is not a piece of paper where a complicated numerator and a complicated denominator can be placed above & below, respectively, one long horizontal division line.
