At construction job for a house, 15 painters were tasked with painting the interior. These painters made up 75% of the painting crew, so how many painters in all worked on this job? Round your answer to the nearest whole number if necessary.

Respuesta :

There are 20 painters in all who worked on this job.

Given:
interior painters = 15 painters
percentage of interior painter = 75% of painting crew

15 is a part of a whole ; 75% is the equivalent of the part in a whole.

To get the whole which is the total number of painters in the painting crew, we divide the part by its percentage.

15 / 75% = 20 painters in a painting crew

To check:
20 x 75% = 15
15/20 = 0.75 x 100% = 75%
