Talking gear ratios and other numbers

okay i found my gear ratio on my axle underneath years of paint, rust, and mud. 3:31 but i found another number 43:13, what is that second number? and i know that in 24 years there really is no telling what kind of mods someone has done to the axles without opening them but lets just pretend that they are still stock and go with 3:31.

The first # 43 is the number of teeth on the ring gear the second # 13 is the number of teeth on the pinion gear. devide 43 by 13 and you get 3:307692 round up to 3:31

43:13 is where the 3.31 comes from
43 teeth on the ring gear divided by 13 teeth on the pinion equals 3.30769 (3.31 to 1 ratio)
Jim types faster than me.
