I've always been confused when calculating percentages. If I want to determine what is 15% of 456, I have to always check if I am using the right method to calculate.

In Excel I use formulas to do the same, but am always wondering things like should I divide or multiply by 100? Where should the numbers go?
So I decided to make a video to remind me how it is done, and hope that this will also help other "percent" challenged folks out there in YouTube land. Here is the video:
