You can put this solution on YOUR website! It took ten men 16 days to paint a house.
Find the no. of man-days required to paint the house
10*16 = 160 man-days
:
At that same rate, how many men would it have taken to finish paint the house in 10 days
let m = no. of men required to do it 10 days
10m = 160
m = 160/10
m = 16 men to do it in 10 days
