Reciprocal 13/15, and change the operation to multiplication.
So we have 39/50 x 15/13
cross out 15, and 50 since they are divisble by 5 so 15 becomes 3, and 50 becomes 10. Also cross out 13 and 39 because they are divisible by 13. So 13 becomes 1, and 39 becomes 3. So now we have 3/10 x 3/1. 3x3=9
