Una de las formas más eficientes para comparar cantidades es el uso de porcentajes.
La razón de un número a cien se llama porcentaje (o tanto por ciento). Cuando se habla de un tanto por ciento, significa que dicho número puede dividirse en 100partes iguales, de las cuales se toma un tanto.
El porcentaje se representa con el símbolo %. Todo porcentaje puede expresarse como una fracción o como un número decimal.
