# How do you know what gear ratio you have?

Divide one teeth count by the other.

Now that you know how many teeth are on each gear, you can find the gear ratio relatively simply.

Divide the driven gear teeth by the drive gear teeth.

Depending on your assignment, you may write your answer as a decimal, a fraction, or in ratio form (i.e., x : y).
