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 it$$s declared. the constructor should contain default values in case no initialzers are provided and should store the function in reduced form. for example the fraction $2/4$ would be stored in the object as $1$ in the numerator and two in the denominator. provide public member functions and perform each of the following tasks: Add:adds two rational numbers. the results should be stored in reduced form. Subtract: subtracts two rational numbers. store the results in reduced form. Multiply: Multiplies two rational numbers. store the results in reduced form. Divide: Divides two rational numbers. Stores the results in reduced form. toRationalString: returns a string representation of a rational number in the form a$/$b$,$ where a is the numerator and b is the denominator. todouble: returns the rational number as a double.
