Question 1022963: If it takes 3 men 2 hours to build a wall, how long would it take 4 men?
Answer by Cromlix(4381)   (Show Source):
You can put this solution on YOUR website! Hi there,
If it takes 3 men 2 hours to build a wall.
How long will it take 4 men
As you have two lots of men this is your ratio.
With 4 men do you think it will take longer or
less time?
It will take less time so you multiply the 2 hours
by 3/4.
3/4 x 2 = 1.5 hours.
(If you had less men, say, 2 men the ratio would have
had the larger number on top 3/2 x 3 = 3 hours)
Hope this helps :-)
