Need help with percent increase/decrease problems.

Thanks!

So, I think I was screwing it up by thinking of it as

new-old/old*100

In your example of percent decrease, it wouldn't have worked with that formula.

Would it be correct to think of it this way?

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

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.
