Explanation:

Step1: Calcular el número de votantes que trabajaron

Multiplicar el número de votantes por la frecuencia relativa.
$50\times0.64 = 32$

Step2: Calcular el número de no - votantes que trabajaron

Multiplicar el número de no - votantes por la frecuencia relativa.
$85\times0.4=34$

Step3: Sumar los dos resultados

$32 + 34=66$

66
