-1 as a denominator changes the sign of the fractions. 1/-2 is the same as -(1/2).

The absolute value of the numerator of a fraction is less than the absolute value of the denominator if and only if the fraction is between -1 and 1.
"Denumerator" is the incorrect but commonly substituted spelling of "denominator". A denominator is the term in the lower part of a fraction, the value by which the numerator is divided. For example, the denominator of 1/2 is 2, and the numerator is 1.
The numerator and denominator are equal to the same value.
An integer is a number that is the quotient of an integer in the numerator and 1 in the denominator. For instance: n / 1 = n is an integer We can think of "integer" as "the value in the denominator divides the value in the numerator". This also gives the integer. For instance: 18 / 2 = 9.
Because the denominator does not express a value, only the size of the parts being added or subtracted. You can think of integers as fractions with a denominator of 1. At any rate, 1/3 plus 1/3 = 2/3, as you can see with any sliced pizza. When you multiply fractions, the denominator is telling you to change the size of those parts, so that 1/2 of 1/3 is 1/6.
