Understanding the Basics

A percentage is a way to express a number as a fraction of 100. It's a dimensionless ratio, meaning it doesn't have units. The symbol "%" denotes percentage. For example, if you want to understand "30 is what percent of 150", it means you want to express the relationship between 30 and 150 as a proportion out of one hundred.

The core concept boils down to understanding the relationship between a "part" and a "whole." When calculating the amount to percentage, you're essentially finding out what proportion the "part" represents within the "whole". Here's the formula:

Percentage = (Part / Whole) x 100
