<PRE><B>Question 1026435</B>
you go from 400 to 40.


the drop in value is 400 - 40 = 360.


360 / 400 = .9


the new value is 90% less than the original value.


the new value is 10% of the original value because 40 / 400 = .10 = 10%.


if you start off with 100% and you wind up with 10%, your drop in value is 90%.


40 is 90% less than 400.
