Denominator
Denominator is the name for the bottom part of a fraction. It tells you how many equal parts make up a whole, and is also used in the name of the fraction: "halves", "thirds", "quarters", "fifths", "sixths" and so on. The reduced fraction for a rational must have an integer denominator. By convention the denominator is made to be positive (any factor of -1 can be multiplied out into the numerator).
The denominator of a fraction can never be zero since a number devided by zero is not defined.
Fractions
In mathematics, a fraction is a concept of a proportional relation between an object part and the object whole. Each fraction consists of a denominator (bottom) and a numerator (top), representing (respectively) the number of equal parts that an object is divided into, and the number of those parts indicated for the particular fraction.
