Hi,
I am having a problem with fractions in my class. The problem is to create a member function to add two fractions and create a member function to subtract two fractions, so far I get..

class fraction{
private:
int Whole;
int Numerator;
int Denominator;
};

int fraction::AddFraction( int x, int y)
{
}

int fraction::SubstractFraction(int x, int y)
{
}

but I cant seem to do the math for the fractions. Can someone help. Thanks
