A fraction with a zero in the numerator equals to what?
It is equal to 0.
How do you set the denominator equal to zero?
You do not. If you do, the expression is undefined: it has no value.
What does it mean when the numerator and denominator are equal?
If they are both zero, the the fraction is undefined. Otherwise it means that the ratio is equal to one.
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.
Why does a fraction equal zero when a zero is in the numerator?
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
A rational expression is undefined whenever its numerator is zero?
false
A fraction with a zero in the numerator equals to what?
It is equal to 0.
Can two fractions with the same numerator and different denominators be equal?
Only if the numerator is zero,
What fraction ois equal to 0?
It is any fraction whose numerator is zero and denominator is not zero.
What can the denominator of a rational expression never equal?
It cannot be zero.

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.

What value of n makes the expression n plus 4 over n-3 undefined?
1
What are the two conditions that will show an expression considered as an absolute value?
You must look at the condition when the expression is greater or equal to zero and the case (condition) when it is less that zero.
