If the ratio of people to machines is always constant then it would take 60 people to run 20 machines if it takes 12 people to run 4 machines.

This problem can be completed by solving this equation"

12 people per 4 machines = x people per 20 machines

or

#12/4 = x/20#

Solving for #x# while keeping the equation balanced gives:

#(20*12)/4 = (20*x)/20#

#240/4 = x#

#x = 60#
