You can put this solution on YOUR website! 4 men do a job in .14 days
Divide by 4 both sides
4/4 men do a job in .14/4 days
1 man does the same job in ..7/2 days
Multiply by 7 both sides
7*1 man does the same job in ..7*(7/2) days
7 men will do the same job in ..49/2 days
7 men will do the same job in ..24 ½ days
