because a fraction means the numerator divided by the denominator. whenever you take zero and divide it by something you will always get zero Ex. 0/4 = 0 0/2935871238957 = 0 0/109 = 0
If the common factor x plus 1 is divided out of the original expression the reduced expression will be equal to the original expression only when x does not equal?
x does not equal -1, because if x is minus 1, x plus 1 is zero and division by zero is not defined.

Numerator can a numerator be 0?
The numerator means the number of. If the number of something is zero there are none of them therefore. the answer would be zero Be careful for the denominator. It the denominator is zero the answer would be undefined for how can you cut a thing into zero pieces.
