A fraction is a number in the form a/b and in this form, a is called the numerator and b is called the denominator. The denominator of a fraction can never be 0. Examples of fractions include 1/3, 19/7, and 1.5/3.5. A fraction here is expressed as an object and generated by passing the fraction's numerator and denominator as arguments to the class constructor. Two methods such as toString( ) and toFloat( ) take cares of displaying the fraction, either as a fraction or a floating-point value.
