Zero can be neither the numerator nor the denominator of a fraction.
zero.
any fraction
The answer depends on the part of the question that is missing.
No. The reason you can multiply a fraction by (x/x) to find an equivalent fraction is because for almost any x, (x/x) = 1. This is not the case for zero. Zero divided by zero does NOT equal 1, so multiplying the fraction by a value not equal to 1 will create a different fraction.
Any fraction that has a zero as the numerator equals zero. Any fraction that does not have a zero in the numerator would be a nonzero fraction.
The fraction is zero. 0 divided by anything except zero is zero.
The rule is if the numerator is zero than the value of the fraction is zero.
Zero can be neither the numerator nor the denominator of a fraction.
"Zero point" is 0. It is an integer, not a fraction.
-9 over anything but zero is a fraction. Division by zero is undefined.
You can't change a fraction when the numerator is zero because no matter what the denominator is the fraction is still zero. A zero denominator is not allowed because you cannot divide by zero.
Zero
No.
It is any fraction whose numerator is zero and denominator is not zero.
a value of zero in the denominator makes the fraction undefined
No, it's zero.
