What about zeros? Any fraction with zero in the numerator is automatically zero, which means it's neither negative nor positive:

(But remember you can't have a zero denominator, no matter what!)

More complicated examples: Keep in mind that the numerator or denominator might be some complicated expression that needs to be simplified first:
