A new method add should be introduced into the class to add two rational numbers. This method should accept another rational number, say rat, as argument and return the sum of the current rational number and rat. Select the correct implementation of this method. Sample behavior of this method is given below:
Input:
a = Rational(10, 2)
b = Rational(10, 3)
c = a.add(b)
c.print_info()
Output:
25/3
