OpenStudy (k12awesomeness):

do i subtract them or something??

rebeccaxhawaii (rebeccaxhawaii):

nope we have to find percent

OpenStudy (k12awesomeness):

yeah, how do we do that? I'm NOT good at this AT ALL...

rebeccaxhawaii (rebeccaxhawaii):

First: work out the difference (decrease) between the two numbers you are comparing. Decrease = Original Number - New Number Then: divide the decrease by the original number and multiply the answer by 100. % Decrease = Decrease ÷ Original Number × 100 If your answer is a negative number then this is a percentage increase.
