It takes 6 workers 3 days to build one house. So the rate of building is:
\n" ); document.write( "1 house/(6 workers*3 days) = 1 house per 18 worker-days
\n" ); document.write( "To build in one day we need
\n" ); document.write( "1 house/18 worker-days * 1 day = 1 house per 18 workers
\n" ); document.write( "Therefore it takes 18 workers to build 1 house in 1 day \n" ); document.write( "

\n" );
