Question 350649
if it takes 4 men to mow 4 lawns in 4 hours then how many men does it take to mow 50 lawns in 50 hours? 
:
Find how many man-hours to mow 1 lawn:  {{{(4*4)/4}}} 4 man-hours to mow 1 lawn
:
then 50 lawns would require: 4 * 50 = 200 man-hrs to do the job
:
let m = no. of men required to do the job in 50 hrs
50m = 200
m = 200/50
m = 4 men to do the job in 50 hrs
