I do believe that Ben's statement is always true because of the fact that when you divide a positive by a negative, or a negative by a positive, it will always equal a negative. For the equation 5.4/-6.8 the answer is -0.79411764705. And the equation -6.8/5.4 is equal to -1.25925925926. It will always equal to less then zero, except when you divide by zero.
