Understanding Percentages

A percentage is a way of expressing a number as a fraction of 100. It's a ratio where the whole is always considered to be 100. The word "percent" comes from the Latin "per centum," meaning "by the hundred."

Formula: Percentage = (Part / Whole) * 100

Example: If you want to find out what percentage 25 is of 200:

  • Part = 25
  • Whole = 200
  • Percentage = (25 / 200) * 100 = 12.5%

Percentages are widely used in various aspects of life, from calculating discounts and taxes to understanding statistics and data. This tool helps you quickly perform these calculations.
