• 2:1

• 3:1

• 1:2

What is the gear ratio of a 15-tooth driver gear and a 45-tooth driven gear?

• 1:2

• 2:1

• 3:1

• 4:1

What is the gear ratio of a 50-tooth driver gear and a 25-tooth driven gear?

• 1:1

How do you calculate gear ratio using the number of teeth?

• gear ratio = (number of teeth on driver gear)/(number of teeth on driven gear)

• gear ratio = (number of teeth on driven gear)/(number of teeth on driver gear)

• gear ratio = (number of teeth on driven gear) + (number of teeth on driver gear)

• gear ratio = (number of teeth on driven gear) - (number of teeth on driver gear)
