\n" ); document.write( "In 1 hour Sarah can do \"1%2F9\" part of job, in x hours she will do \"x%2F9\"part of job
\n" ); document.write( "In 1 hour Floyd can do \"1%2F15\" part of job, in x hours he will do \"x%2F15\" part of job
\n" ); document.write( "Together in x hours they will finish all job
\n" ); document.write( "The equation
\n" ); document.write( "\"x%2F9%2Bx%2F15=1\" multiply by 45
\n" ); document.write( "\"5x%2B3x=45\"
\n" ); document.write( "\"8x=45\"
\n" ); document.write( "\"x=45%2F8\"=5\"5%2F8\"
\n" ); document.write( "in 5\"5%2F8\" hours they will clean an attic together
