For a survey, a company decided to call 7 out of every 5000 people. how many people should be called in a town of 78000 people?

Respuesta :

This is an easy one!

7:5000 :: x:78000

(7)x(78000) = 5000x

(7 x 78000)/5000 = x

109.2 = x

Since they cannot call 0.2 people, we have to round it! So, 109 people!
