Question 1189730
<pre>
Instead of doing your homework for you, I'll do another one exactly
like it with different numbers.
</pre>
3 men can do a piece of work in 9 days. How many days would it take 
9 men at the same rate
<pre>
The more the men the fewer the days, so days and men are inversely 
proportional.

{{{Days=k/Men}}}
{{{9=k/3}}}
{{{27=k}}}

{{{Days=27/Men}}}
{{{Days=27/9}}}
{{{Days=3}}}

Now do yours the same way.
