9.6 ( Rational Class) Create a class called Rational for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private data of the class the numerator and the denominator . Provide a constructor that enables an object of this class to be initialized when its declared. The constructor should contain default values in case no initializers are provided and should store the fraction in reduced form. For example, the fraction 2/4 would be stored in the object as 1 in the numerator and 2 in the denominator . Provide public member functions that perform each of the following tasks: A. add Adds two Rational numbers. The result should be stored in reduced form. B. subtract Subtracts two Rational numbers. Store the result in reduced form. C. multiply Multiplies two Rational numbers. Store the result in reduced form. D. divide Divides two Rational numbers. The result should be stored in reduced form. E. toRationalString Returns a string representation of a Rational number in the form a/b , where a is the numerator and b is the denominator. F. toDouble Returns the Rational number as a double .
