Uniform rates for task completion, R*T=J, rate, time, quantity of jobs. Your example has J=1. The job is, "paint a house".
The first clause gives the rate for 6 men as jobs per day. The rate for just 1 man alone is jobs per day.
Now you want a number of men, N, to spent 14 days to do the one job.
;
and you are asked, what is N.
