If the OfficeJet printer does its' job in 12 min., then it does 1/12 job per minute. The Laser jet does 1/8 jobs per minute. Therefore, adding them together, we get:\r
\n" ); document.write( "\n" ); document.write( "1/8 + 1/12=1/n
\n" ); document.write( "3/24 + 2/24=1/n
\n" ); document.write( "5/24=1/n
\n" ); document.write( "5n=24
\n" ); document.write( "n=24/5 minutes working together!!!!!!
\n" ); document.write( "
\n" );
