To change a number to a percentage, just multiply by 100 and slap a % sign on the end. That’s it. Seriously.
Take the number 0.42. Multiply by 100? You get 42—the answer to everything in The Hitchhiker’s Guide to the Galaxy. Now it’s 42%. Deep, right?
What about a whole number, like 5? 5 × 100 = 500%. That’s enough percentage to cover five whole pizzas. You’re basically a math magician now.
But Wait—Why Does This Work? (The Fun, Weird Reason)
Percentages are just fractions with a fancy hat. “Percent” literally means “per hundred.” So when you multiply by 100, you’re asking: “How many out of 100 is this?”
Imagine you have a bag of 100 gummy bears. If you have 0.5 of that bag, you have 50 gummy bears. That’s 50%. Easy, and delicious.
The trick is that every number is a fraction. Even the number 1 is secretly 1/1. You’re just scaling it up to the “out of 100” world. It’s like sending your number to a universe where everything is measured in slices.
