It’s a way of expressing a portion of something in relation to the whole. So when you hear someone say “20%,” they’re talking about 20 parts out of 100.

2. Basic Percentage Formula

To work out a percentage, you’ll need a simple formula:

Percentage = (Part / Whole) × 100

This formula helps you find what portion a certain number represents out of a whole.

Now, let’s put that formula to work. Say you want to find out what 30% of 200 is. Here’s how you do it:

So, 30% of 200 is 60.
