Reading Gear Ratios

[Blackened]

I always see Gear Ratios in mags and I never know what they mean can someone teach me how to read them.

Pick a number, any number ... :L

Say you have gears that are marked "3.73"; that means the driveshaft (pinion gear) rotates 3.73 times while the axle/wheel (ring gear) makes one revolution.

Wait I thought that Gear Ratios was basicly telling you the MPH to shift to the next Gear? I also didn't understand what you were talking about, I don't know all that much of parts and stuff in cars, I just Know a little more then the average person.
