Importante

Cuando multiplicas o divides fracciones el resultado debe estar simplificado.

¿Cómo simplificamos una fracción?

Para simplificar una fracción debo buscr un número que sea distinto de 1 y que sea capaz de dividir al numerador y al denominador al mismo tiempo.

$\frac{40}{45}\div5=\frac{8}{7}$ Cuando ya no hay ningún número que sea capaz de dividir a númerador y denominador, podemos decir que encontramos una FRACCIÓN IRREDUCIBLE
