    Gcf lcd

    A large gear is used to turn a smaller gear. The large gear has 60 teeth and makes 12 revs/min; the smaller gear has 24 teeth. How fast does the smaller gear turn...explain your reasoning.

    can someone please tell me if my reasoning is correct here?

    60 teeth/24 teeth= 5/2

    so the smaller gear is going 5/2 *12 revs/min = 30 revs/min
