como poner fracciones en la calculadora

Escríbelos en paréntesis, como éste:

(1/4) = $$\left({\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right)$$

(1/4) / (1/4) = $${\frac{\left({\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right)}{\left({\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right)}} = {\mathtt{1}}$$

Es incorrecto escribirlo sin paréntesis: 1/4 / 1/4 = $${\frac{{\frac{{\frac{{\mathtt{1}}}{{\mathtt{4}}}}}{{\mathtt{1}}}}}{{\mathtt{4}}}} = {\frac{{\mathtt{1}}}{{\mathtt{16}}}} = {\mathtt{0.062\: \!5}}$$
