A percentage is just a fancy way of saying “out of a hundred.” Think of it like a slice of pie—but the pie is always cut into 100 perfect pieces. If you eat 25 of those pieces, congrats, you’ve eaten 25% of the pie. Don’t worry, I won’t judge your dessert choices.
Now, how do you turn a boring old number into a percentage? It’s easier than you think. And no, you don’t need a calculator that costs more than your rent.
Step one: Find your fraction
First, you need a part and a whole. Let’s say you scored 18 out of 20 on a quiz. That’s your part (18) and your whole (20). Write it as a fraction: 18/20. Simple, right? You’re basically saying, “I got 18 of the possible 20.”
But wait—fractions are so last century. We want that % sign. So, how do we get there? We multiply the fraction by 100. Yes, it’s that cheeky. 18 divided by 20 is 0.9. Then 0.9 times 100 gives you 90. Boom, you’ve got 90%. You’re basically a genius.
