Adelyn Haas · Answer 1

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%
