David moved from a house that is 89 miles from his workplace to a house that is 51 miles away from his workplace. What is the percent decrease in the distance from his home to his workplace?

Because all percentages are out of 100, nothing can physically be over 100%, though it is used frequently in hyperbolic sentences and exaggerated statements.
