Percentages are a way to show how much of something you have out of a total, using 100 parts as the whole. For example, in the video, if a pizza is cut into 4 slices and you eat 1 slice, you have eaten 25% of the pizza because 1 out of 4 slices is the same as 25 out of 100 parts. If you eat 2 slices, that means you ate 50% (or half) of the pizza. Eating 3 slices is 75%, and eating all 4 slices is 100%, or the whole pizza.

Percentages work with anything, not just pizza. If you eat the whole apple, that's 100% of the apple. If you finish your dinner, that's 100% of your dinner. So, a percentage tells how much of something you have out of the whole, using the idea of “parts out of 100”.
