What is a Percentage?

A percentage is a way of expressing a number as a part of a whole, specifically out of 100. It is represented by the symbol "%". Percentages are a useful tool for comparing proportions and understanding ratios in a simple, standardized format.

Understanding Percentages:
  • Basic Definition: A percentage represents a fraction of 100. For example, 50% means 50 out of 100, or half.
  • Conversions: To convert a fraction or decimal to a percentage, multiply by 100. For instance, 0.75 becomes 75%.
  • Usage: Percentages are widely used in everyday life, including in financial calculations, statistics, shopping discounts, academic scores, and more.
Examples:
  • 50%: This means half of a total amount.
  • 25%: This represents one-quarter of a total amount.
  • 100%: This signifies the entire amount.
