At a snack store 7/12 of the customers bought pretzels and 3/10 of those customers bought low salt pretzels. bill states that 7/30 of the customers bought low salt pretzels. does bill statement make sense? explain

Bill's statement does not make sense because it is incorrect.

To be correct, Bill would have to say that 7/40 of the customers bought low salt pretzels, but instead he had said 7/30.
