Exercise 5 A rational number is a number that can be represented as the ratio of two integers. For example, 2/3 is a rational number, and you can think of 7 as a rational number with an implicit 1 in the denominator. 1. Define a class called Rational. A Rational object should have two integer instance variables that store the numerator and denominator. 2. Write a constructor that takes no arguments and that sets the numerator to o 3. Write an instance method called printRational that displays a Rational in 4. Write a main method that creates a new object with type Rational, sets its and denominator to 1. some reasonable format. instance variables to some values, and displays the object
