Can you spin it?? If so, count the teeth on the ring gear and divide that number by the number of teeth on pinion gear to get ratio

I know usually there is a stamp on the pinion gear which would tell you the ratio!!!
For example, the 4.10 ratio ring gear stamping is 41-10 !!!

what is it for 4.11 / 4.88 and 5.13 ratio ???
