Here’s the big secret: every percentage is just a fraction turned into a friendly number out of 100. To convert a regular number—like 0.75 or ½—into a percent, you simply multiply it by 100. That’s it. Really.
For example, if you have the number 0.42, multiply it by 100 and you get 42%. See? You just became a percentage wizard in two seconds flat. Poof!
What About Numbers Like 1.5 or 3?
Don’t panic—this works for bigger numbers, too. Take 1.5. Multiply by 100 and you get 150%. That means you have more than a whole of something, which is awesome if you’re talking about a double batch of cookies. And 3 becomes 300%—three times the fun!
Think of it this way: percentages are just numbers on a confidence scale from 0 to 100 (or beyond). A 0% is a total shrug, and a 100% is a mic-drop moment. Every number you convert is just finding its place on that scale.
