Ok, I know it's on this site somewhere and I've been searching for about 20 minutes and still can not find it!

Using the numbers stamped on the ring gear how do you calculate the ratio?

Do you just divide the two numbers such as:

39-10 = 3.9

37-11 = 3.36

First number divided by second.

37:11 = 3.36

39:11 = 3.56

37:10 = 3.70

39:10 = 3.90

Perfect, thank you!! That's what I thought, just wanted to confirm.
