What is a percent and why is it out of one hundred?

Here's a tiny word that runs the world: percent. It's hiding on your phone battery, on sale tags, on weather forecasts, on test scores. It looks fancy, but really it's just a clever way of answering one nosy little question — "out of the whole thing, how much?"
Imagine you and a friend each baked cookies. You ate 7 of yours, your friend ate 30 of theirs. Who feasted more? You can't tell yet — because you don't know how many each of you started with. Numbers alone are sneaky. They only mean something when you know the size of the whole pile.
