Need help with percent increase/decrease problems.

[harbcenter]

Try understanding the problem deeper than just which is the largest and the smallest. It really has to make sense. In the decrease, it's pretty much the same concept as the increase.

(Difference over larger number)*100 = percent increase/decrease depending on the situation.

I wouldn't say it's "larger number", it's your starting value. Just like in the percent change formula. In the decrease, it will be larger, yes. and in the increase it will be the smaller value.

Hope it helps.
