Calculate the gear ratio below if the blue gear is the driver

The correct option is;

1

Explanation:

The number of teeth on the blue, driver, gear = 20 T

The number of teeth on the yellow, driven, gear = 20 T

In order to find the gear ratio of a gear train, the ratio of the number of teeth on the driven gear to the number of teeth on the driver gear gives the gear ratio

Therefore, the gear ratio = 20 T/(20 T) = 1
