Un vaso contiene leche hasta los 3/5 de su capacidad. si echa un 1/7 mas, es seguro que la leche
Yanka [14]

Answer:

<em>De las opciones presentadas, la correcta es la D.</em>

Step-by-step explanation:

<u>Suma de fracciones</u>

Dado que un vaso contiene 3/5 de su capacidad con leche, aún tiene libre una fracción que puede ser llenada.

Si se echa 1/7 más de leche, vamos a encontrar si la suma de las dos cantidades supera al 100% o también al número 1 que es la representación del vaso completo.

Sumemos:

\displaystyle \frac{3}{5}+\frac{1}{7}=\frac{3*7+1*5}{35}=\frac{21+5}{35}=\frac{26}{35}

Como el numerador es menor que el denominador, la fracción es menor que 1 y aún cabe más leche en el vaso. Calculando el valor aproximado:

\displaystyle \frac{26}{35}\approx 0.74

Lo cual representa un 74% aproximadamente.

De las opciones presentadas, la correcta es la D.
