4 1/3
Hope this helped :) 
The explanation:
3 goes into 13 4 times. So 4 is your whole number.
You have 1 number left over so that is your numerator.
Your denominator does not change.
You can not simplify any more. 
4 1/3 because 3 times x equals the closest to 13. 3 times four is 12 and it is the closest to thirteen as it can get being under 13, that remainder or remaining one stays one. 4 1/3
