Understanding Percentages
A percentage is a way of expressing a number as a fraction of 100. The term “percent” means “per hundred” and is represented by the symbol %.
Percentages are used in many real-world applications including discounts, taxes, interest rates, statistics, and grade calculations.
To convert a percentage to a decimal, divide by 100 (e.g., 25% = 0.25). To convert a decimal to a percentage, multiply by 100 (e.g., 0.75 = 75%).
When calculating percentage change, always use the original value as the base for comparison. Percentage difference uses the average of both values as the base to avoid directional bias.
