When a machine has two gears of different sizes, the smaller gear turns faster than the larger gear. When the first gear (the driver or input gear) turns, the second gear (the driven or ouput gear) turns in response. The difference between the speeds of the two gears is called the speed ratio or gear ratio.

So a gear with 24 teeth will provide a gear reduction of 24:1. For a multi-start worm, the gear reduction equals the number of teeth on the gear, divided by the number of starts on the worm. (This is different from most other types of gears, where the gear reduction is a function of the diameters of the two components.)
