Conversor de Fração para Porcentagem

The Fraction to Percentage Converter transforms any fraction, expressed as numerator over denominator, into its equivalent percentage. The calculation is simple: divide the numerator by the denominator and multiply the result by 100. For example, the fraction 3/4 becomes 75%, since 3 ÷ 4 = 0.75 and 0.75 × 100 = 75. The tool accepts positive and negative numbers, as well as decimal values in the numerator or denominator.

This calculator is useful in many everyday situations, such as calculating discounts on purchases (e.g., a 1/4 discount equals 25%), interpreting test scores (getting 17 out of 20 questions right corresponds to 85%), or analyzing statistical and financial data. It eliminates the need for manual calculations, providing the result instantly.

When using the tool, remember that the denominator cannot be zero, as division by zero is undefined. Also, fractions can result in percentages greater than 100% if the numerator is larger than the denominator, such as 5/4 = 125%. The calculator also handles negative fractions, generating negative percentages. Always double-check the entered fraction to avoid interpretation errors.
