According to the picture on the website for 5 rings.
a=9
b=4
c=1
d=8
e=3
f=2
g=5
h=6
i=7
I figured out that the total had to be between 10 and 15 so i tried 13 and created the only possibilities that could add up to 13, which were 9 and 4, 6 and 7, 8 and 5, I tried with many different combinations using the possibilities and I eventually solved the problem.
