/**
Fractions Average
Write a program (FractionAverage) that reads three pairs of numbers,
treats them as fractions, and prints their average, as a fraction.
Here is a sample run:
Enter a numerator: 1
Enter a denominator: 2
Enter a numerator: 3
Enter a denominator: 4
Enter a numerator: 2
Enter a denominator: 3
The average of 1/2, 3/4, and 2/3 is 23/36
Your program will make use of the services of the supplied Fraction class.
