Answer:

150 hombres juegan baloncesto.

Step-by-step explanation:

En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.

Paso 1

Encontramos el número de estudiantes que son mujeres

= 1/3 × 315

= 105 mujeres.

Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:

= 315 - 105 mujeres

= 210 hombres

Paso 2

2/7 de los hombres juegan fútbol y el resto baloncesto.

Esto significa que 2/7 de 210 hombres juegan al fútbol

= 2/7 × 210 hombres

= 60 hombres

Por tanto, 60 hombres juegan al fútbol.

Paso 3

También se nos dice que el resto juega al baloncesto.

El número de hombres que juegan baloncesto se calcula como:

210 - 60

= 150 hombres.

Por tanto, 150 hombres juegan baloncesto.
