(69-82)/82 = -16%
This is to two significant figures which are all that are necessary. Any further precision is utterly meaningless!
Also, it is important that you set the ratio up properly with the old figure (82) subtracted from the new (69). It is a negative change.

Subtract 82 - 69 = 13 now divide by the original 13 /82 = 15.9 %
Hope This Helps!

First, find the difference. 82 - 69 = 13.
Then find how much 13 is out of the original number ( 82. )
so 13 = 82x ( x representing percentage. )
then get x by it self. divide both sides by 82.
13/82 approximately 15.9%

% of change: (change/old)*100 = (-13/82)*100 = -.1585 = -15.85%

Simply subtract the old value from the new value, then divide by the old value. Multiply the result by 100 and slap a % sign on it. That's your percent change.
15.85%
