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 1%2F21 jobs per day. The rate for just 1 man alone is %281%2F6%29%281%2F21%29 jobs per day.

Now you want a number of men, N, to spent 14 days to do the one job.
highlight%28N%281%2F%286%2A21%29%29%2A14=1%29;
and you are asked, what is N.
