Plz help me

Answer 1

The total number of social worker doing part time work is 9 .

Explanation:

Given as :

The percentage of social worker on which Cole surveyed = 20 %

I.e 20 % of the social worker

Or the number of social worker = 45

Let The number of social worker working part time = x

So, x = 20 % of the total social worker

I.e x = 0.2 × 45

∴ x = 9

So , out of total 45 social worker , the number of social worker working part time = 9

Hence The total number of social worker doing part time work is 9 . Answer
