You can put this solution on YOUR website! If only 1 of the men, then the work rate is of the group of 12 men. This means, 1 man goes at the rate of houses per hour. The question is about the rate for 9 men:
Knowing their rates are additive, houses per hour, which using the reciprocal, is 36 hours to paint one house.
You can put this solution on YOUR website! find out the man hours needed to paint the house
12*27=324 man hours needed to paint the house
there are only 9 men available to do the 324 man hours
324/9=36 hours for 9 men
