Question

An insurance office has 70 employees. If 56 of the employees have cellular phones, find (a) the portion of the employees who have cellular phones and (b) the portion of the employees who do not have cellular phones.

Answer 1

In an insurance office with 70 employees where 56 have cellular phones, the portion with phones is 80% (0.8), and the portion without phones is 20% (0.2).

Step-by-step explanation:

When an insurance office has 70 employees and 56 of them have cellular phones, we can calculate:

(a) The portion of the employees who have cellular phones

The portion is found by dividing the number of employees with phones by the total number of employees:

Portion with phones = number with phones / total number of employees

= 56 / 70

= 0.8 or 80%

(b) The portion of the employees who do not have cellular phones

To find this, subtract the portion with phones from 1 (or 100%):

Portion without phones = 1 - portion with phones

= 1 - 0.8

= 0.2 or 20%
