Answer:
3/13 is the reduced form
Explanation:
k so take the greatest common factor/GCF which is the number that divides into the other number (sorry that was bad) what I mean is like:
9/39 well 3 goes into 9. 3*3=9 what you would do is 9/3=3 and whatever you do to the top you HAVE to do to the bottom so... 39/3=13 since nothing divides by 13 or 3 that is your answer 3/13
