Percentage vs Fraction: When to Use Which Representation

Understand the difference between percentages, fractions, and decimals, and when each representation is the clearest choice.

Meaning

A percentage is a fraction out of 100. 25% is exactly 1/4, and 0.25 is the decimal form.

Percentages are intuitive for everyday comparison ('45% off'). Fractions are clearer for exact ratios like 1/3.

Fractions are exact (1/3 is never rounded). Percentages and decimals round to a fixed number of digits.

Percentage: discounts, growth rates, statistics. Fraction: measurements, recipes, exact ratios.
