What Is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. The word comes from the Latin per centum, meaning βby the hundred.β Percentages are used everywhere in daily life β from calculating tips and discounts to understanding interest rates, test scores, and statistical data.
The basic formula is: Percentage = (Part Γ· Whole) Γ 100. For example, if you scored 45 out of 60 on a test, your percentage is (45 Γ· 60) Γ 100 = 75%. Conversely, to find a percentage of a number, divide the percentage by 100 and multiply: 20% of 150 = 0.20 Γ 150 = 30.
Understanding percentages helps you make better financial decisions β comparing loan interest rates, evaluating investment returns, calculating sales tax, or determining how much to tip. In business, percentages are essential for analyzing growth rates, profit margins, and market share. In academics, they standardize scores across different grading scales.
