number of workers, n
rate for n workers, nr


---------------------------------------------------------------------------
It takes 3 people to clean a pool in 4 hours. How many people do we need to clean 6 pools in 8 hours?
-------------------------------------------------------------------------


{{{3*r*4=1}}}---------------the job of cleaning ONE pool.


{{{n*r*8=6}}}--------------the question


Divide the second equation by the first equation and solve for n.
{{{(8rn)/(3*4*r)=6/1}}}

{{{(8n)/(3*4)=6}}}

{{{n=6((3*4)/8)}}}

{{{n=6(3/2)}}}

{{{highlight(n=9)}}}
