Question 1003152
is 4 men can do 2 rooms in a certain amount of time, then 6 men should be able to do 3 rooms in the same amount of time.


4 men for 2 rooms means each room takes 2 men.


add 2 more men then you are adding one more room.


6 men can do 3 rooms in the same amount of time.


you get the ratio 4 is to 2 as 6 is to x, where x represents the number of rooms.


that ratio can be shown as 4/2 = 6/x


cross multiply to get 4x = 12


solve for x to get x = 3
