Sergeeva-Olga [200]

Usando proporciones, hay que con 200 pesos mx se pueden comprar 0.0645 yenes.

<h3>¿Qué es una proporción?</h3>

En este problema, hay que un yene cuesta $0.17, enquanto $1 = 3100 pesos. Por eso, cada yene es equivalente a 3100 pesos.

Por eso, la <em>regla de tres</em> es:

1 yene - 3100 pesos

x yenes - 200 pesos

Aplicando multiplicación cruzada:

3100x = 200

x = \frac{200}{3100}

x = 0.0645

Con 200 pesos mx se pueden comprar 0.0645 yenes.
