class RationalNumber 1
Need to create a class RationalNumber(fractions) with the following capabilities:
* Create a constructor that prevents a 0 denominator in a fraction.
* Design the add, sub, mul, and division functions for this class.
* Design the functions for the relational and equality operation in this class.
Need code listed below modified that will generate this output:
5/3 addition 3/2 = 19/6
5/3 subtraction 3/2 = 1/6
5/3 multiplication 3/2 = 5/2
5/3 division 3/2 = 10/9
5/3 is:
!= 3/2
!= 3/2
This is what I have so far.

5/3 addition 3/2 = 19/6
