I have add the two functions the add and subtract I have to now add the multiply and divsion functions can someone help

This is not a code snippet, but a normal c++ question.
[code]
#include<iostream>
using namespace std;

class fractions
{
public:
	fractions fractions :: operator+(fractions f);
	fractions addFraction(fractions);
	fractions subFraction(fractions);
	fractions();
	fractions(int, int);
	void printFraction();
private:
	int numerator;
	int denominator;
};

//method to add two fractions
fractions fractions :: addFraction(fractions f)
{
	fractions temp;
	temp.denominator = denominator * f.denominator;
	temp.numerator = numerator * f.denominator + denominator * f.numerator;
	return temp;
}
//method to subtract two fractions
fractions fractions :: subFraction(fractions f)
{
    fractions temp;
    temp.denominator = denominator * f.denominator;
    temp.numerator = numerator * f.denominator - denominator * f.numerator;
    return temp;
}

//method to add two fractions
fractions fractions :: operator+(fractions f)
{
	fractions temp;
	temp.denominator = denominator * f.denominator;
	temp.numerator = numerator * f.denominator + denominator * f.numerator;
	return temp;
}
//method to subtract two fractions
fractions fractions :: operator+(fractions f)
{
	fractions temp;
	temp.denominator = denominator * f.denominator;
	temp.numerator = numerator * f.denominator - denominator * f.numerator;
	return temp;
}

fractions::fractions()
{
	numerator = 0;
	denominator = 1;
}

fractions::fractions(int n, int d)
{
	numerator = n;
	denominator = d;
}

void fractions::printFraction()
{
	cout <<numerator<<'/'<<denominator<<endl;
}

void getFraction(int &numerator, int &denominator)
{
    cout<<"Please enter numerator";
	cin >>numerator;
	cout<<"Please enter denominator";
	cin >>denominator;
}

int main()
{
	int n,d;
	fractions f1(1,2);
	fractions f2(3,4);
	fractions f3;
	fractions f4;
    getfraction(n,d);
	fractions f5(n,d);
	

	f3 = f1.addFraction(f2);
	f4 = f3 + f1;
	f3.printFraction();
	f4.printFraction();
	system("pause");
	

}
