Changing a whole number to a percent is embarrassingly simple. You just multiply the number by 100 and slap a percent sign on the end. That’s it. No incantations, no blood moons required.
Think of it this way: every whole number is secretly a decimal in disguise. The number 7 is actually 7.00, which is just 7.00 out of 1. When you multiply by 100, you’re basically asking, “Hey, if I had 100 of something, how many would I have?” And the answer is 700. So 7 becomes 700%. You now officially have seven times more percent than you had numbers.
But Wait—Why Does This Work? (A Quick, Painless Detour)
Percent literally means “per hundred.” So when you have the number 3, you’re saying, “I have 3 things out of 1.” But we want to know how many you’d have if the basket had 100 slots. That’s why you multiply: 3 × 100 = 300. You’d have 300 things in a 100-slot basket—which is absurd, but also glorious.
This is why a whole number percent always ends up over 100%. If you see 50% on a test, that’s a half. But if you see 200%, you’ve either done double the work, or you’re a wizard. Congratulations.
