Zero
The denominator.
The name is zero.
YES a fraction can be a denominator.
Never. You could write a fraction as a mixed fraction if you like and then the mixed fraction would have a different denominator (e.g.: 23/2 = 11 1/2)
A fraction is really the numerator divided by the denominator. When you divide two negatives together you get a positive, so, you automatically change it to positive.
The denominator should be the same as the denominator of the fraction.
The denominator tells you the total of the pieces in the fraction.
the denominator
you multiply the numerator by the numerator and the denominator by the denominator.
The upper part of a fraction is its numerator and the lower part of a fraction is its denominator.
a fraction that has a numerator equal to the denominator is one: a fraction who's numerator is greater that the denominator is an improper fraction.
