540 men can construct a building in 7 months.how many men should be removed from work to finish the building in 9 months? ( please someone explain it so that i can learn it)
154 men should be removed because if it takes about 77 men to construct a building in one month then you added two months to 7 so I think you should remove 154 men. (you cannot guarantee a 12 yr olds answer but I'm pretty smart)
