Question

Add a construction job for a gallery, 105 painters were tasked with painting the interior. These painters made up 75% of the total painting crew how many painters in our on this job

Answer 1

Let P stand for the Paint crew...and you know that 75% of that crew = 105 people. So we know that...
P x .75 = 105
Divide both sides of the equation by .75 to solve for P...
P = 105/.75 = 140
So the total paint crew has 140 painters.
