If m workers can complete a job in d days, how many days will it take n workers, working at the same rate, to complete one-third of the job? Express your answer as a common fraction in terms of d, m and m, in alphabetical order where applicable.

Each worker m works d days, so the total amount of days worked is m * d. 1/3 of the work would be $$\frac{md}{3}$$. This means that it would take n workers $$\frac{md}{\frac{3}{n}}$$ which simplifies to $$\frac{md}{3n}$$.
