I have a program due that requires me to deal with adding, multiplying, dividing, subtracting, and simplifying fractions. I'm stuck on the simplifying part. This is a generic coding for the simplification part:

(Toggle Plain Text)

class Reduce
{
	int den, num, i = 2, cd = 0;
	Reduce(int n, int d)
	{
		num = n;
		den = d;
	}
	

	void reduction()
	{
		do
		{
			if ((den % i == 0) && (num % i == 0))
				cd = i;
			else i++;
		}
		while (cd == 0);

		System.out.println(cd);

		num /= cd;
		den /= cd;

		System.out.println(num + "/" + den);
	}
}

class Test
{
	static public void main(String[] a)
	{
		
		Reduce r1 = new Reduce(3,9);
		r1.reduction();
	}
}

It seems to work with fractions like 3/9 and 2/6, fractions that are able to be simplified. If I try with say 3/8, the output is 1/4. I was wondering if anyone out there can help me figure out why it is doing that. It's frustrating me a lot and I would like to finish this program soon.

I'd say an easier way of doing this would be to just divide both numbers by their GCF. Finding the GCF will proabably be the hardest part.

Thanks for the response, I'll see what I can do about that and post back.
