So for percent incerease and decrease you could use N-O/O 100
(NEW-OLD, DIVIDED BY OLD TIMES BY 100.

450 IS OLD AND 360 IS NEW SO,,,,,,,,,,,,,,,,,,,,,,,,,, 360-450/450 100 
THAN YOU GET -20... BUT YOU CAN'T SAY -2O SO YOU SAY 20% DECREASE

20% DECRASE IS YOU ANSWER(YOU ALWAYS HAVE TO PUT INCREASE OR DECREASE)

HOPE IT HELPS :P
