❔ Looking to turn this GUI integer calculator into a Fraction calculator using the provided class
Final project for school, need to create a GUI fraction calculator. I have a GUI integer calculator already built, and a Fraction class already built. Currently stuck on where to even begin to have the GUI calculate fractions vs. integers.

Fraction Class

private int denominator = 1;
public int CompareTo(object rightObject)
{
// typecast the object parameter to a Fraction
Fraction rightFrac = (Fraction)rightObject;
// get both Fractions as (comparable) doubles
double f1 = (double)(this.numerator) / (double)(this.denominator);
double f2 = (double)(rightFrac.numerator) / (double)(rightFrac.denominator);
// compare the 2 doubles
int retVal = 0;
if (f1 < f2)
retVal = -1;
else if (f1 == f2)
retVal = 0;
else
retVal = 1;
return retVal;
