Se puede pasar 11/20 a fraccion mixta?

Shtirlitz [24]

La fracción 11/20 no puede ser una fracción mixta ya que es una fracción propia es decir el numerador es menor al denominador.

Digamos que si usaramos el recíproco de la fracción si se podría pasar a mixta ya que en ese caso seria impropia.

Solo las fracciones impropias pueden ser mixtas.

Por ejemplo si invertimos la fracción :

$\:\: \: \: \: \: \: \: \boxed{ \bold{\frac{20}{11} = 1 \: \: \frac{9}{11} }}$
