Java newbie seeks easy solution I cannot find!

Question

How would I print a fraction ( it MUST be a fraction ) to be displayed in the Java application?
For example I take the average of three numbers and the result is 5 1/3.
I have been fooling around with % 3 ( in my case it will always be a number over 3 because for this particular program I am taking the average of only three numbers ) . Using % 3 allows me to get the remainder number that will be displayed on the upper part of the fraction but no matter what I do I cannot get that number to be represented OVER 3.
I have been trying
system.out.println((average / 3) % / 3);
(average is where it takes the average of my integers)
But it does the actual math instead of printing out the remainder over 3. When I throw in quotation marks it doesn't work either. I have been looking through a few books and I have come up blank.
I am totally new to Java so anything you throw at me will be much appreciated. Thank you.

I guess very simply put is how would I convert a decimal to a written
out fraction in Java? IE 3.3333333 -> 3 1/3spoiler:public void printAsFractionDiv3(int n) {
   int f= n%3;
   System.out.print(n/3);
   if (f != 0)
      System.out.print("+"+f+"/3");
}kind regards,
