Display rational numbers using fprintf

I am using fprintf to write my answers to a file. I have numbers such as: 3/7,3/11,6/37... I tried different formats but every time it always changed it to a numeric value. Then I tried format rat before fprintf. This didn't work neither. How can I display a rational number using fprintf?

T = 1/3;
fprintf('The number is: %s\n',strtrim(rats(T)))

[n,d] = rat(YourNumericValue);
fprint(fid, '%d/%d', n, d)
However, if you have the numerator and denominator already available, then
fprintf(fid, '%d/%d', numerator, denominator)
which is what I think you probably want to do, if I remember your earlier question properly.
MATLAB is not designed to be able to tell the difference between 3/4 and 6/8: it will calculate the binary equivalents of the result and use that binary result, except in the Symbolic Toolbox where it will reduce the fraction to lowest terms and use the reduced rational fraction.
