    We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:

    140/84=100/x (this equation is basically saying if 140 is 100 (%) what would 84 be?)

    solving for x here gives us x = (84 X 100) / 140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.

    Let me know if I can clear anything else up.
