They are two classes. Fraction and calculator. Fraction does things like add, multiply....
The calculator class is supposed to call the methods in the Fraction class and output the data. The problem is i can't figure out where to put the calculator class so that it can output data. Here is the code for the fraction and calculator class. I have tested the calculator code in the main of the fraction and it works. I can't use inheritance due to assignment specifications.
