The ratio of teeth between the smaller and larger gears is the ratio of reduction. Example: take a small gear with 25 teeth and make it turn a big gear with 100 teeth. One revolution of the big gear means that the small gear has turned four times which gives us a 4:1 mechanical advantage, also know in gears as 4:1 reduction.
