if the turns of the output gear over the turns of the input gear is equal to the number of teeth on the input gear over the number of teeth on the output gear, the input gear has 36 teeth and the output has 10, the output gear has turned twice as much as the input gear, how many times has the output and input gear moved?

this question really confused me... and the rest of the class..

    It confuses me. The ratio of turns is 3.6 whatever the input turns, the output is 3.6 times that.
