First calculate the time worked in the office. Eight hours is the difference between 5:30pm (17:30) and 9:30am. But subtract half an hour from that because of the lunch break. So seven and a half hours is the time worked in the office.\r

\n" ); document.write( "\n" ); document.write( "The ratio can be reduced by .5, so the final answer is \"1%2F15\"
\n" ); document.write( "
