Question

You need workers to finish a large project. On a list of 30 possible workers, 9 are not available. You need only 1/3 of the remaining workers for the project. How many workers do you need?

Answer 1

Answer:

9 are not available are I need 9 workers

Answer 2

Answer:

Number of workers needed = 7

Step-by-step explanation:

Given total number of workers = 30

        number of workers not available = 9

Remaining number of workers = total number - workers not available

                                                   $= 30-9=21$

Given, number of workers required = 1/3 of the remaining workers

                                                           $= \frac{1}{3} \times 21=7$

Number of workers needed = 7
