Calculate a Ratio in C#

Question

I thought this would be simple, but searching Google didn\'t seem to help.

I\'m basically trying to write a function which will return a ratio as a string (eg 4:3) w

Answer 1

With Using following 2 functions, you will be able tow get ratio of two numbers without using division operations.

static int GCD(int p, int q)//find greatest common divisor
{
    if (q == 0)
    {
        return p;
    }

    int r = p % q;

    return GCD(q, r);
}
static string  FindRatio(int num1, int num2)
{

    string oran = "";
    int gcd;
    int quotient = 0;
    while (num1 >= num2)
    {
        num1 = num1 - num2;
        quotient++;
    }

    gcd = GCD(num1, num2);

    //without using division finding ration of num1 i1
    int i1 = 1;
    while (gcd*i1 != num1)
    {
        i1++;
    }
    //without using division finding ration of num1 i2
    int i2 = 1;
    while (gcd * i2 != num2)
    {
        i2++;
    }

    oran = string.Concat(quotient, " ", i1,"/",i2);
    return oran;
}

Output will be as follow:
coff num1 / num2
