\r\n" );
document.write( "Since 12 Workers can finish a third of a house in 15 days, the rate of work of one worker is r =  =  of the house per day.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Let x = \"How many workers must be added to finish the rest of the house in the next 18 days\"\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then we have this equation\r\n" );
document.write( "\r\n" );
document.write( " = .\r\n" );
document.write( "\r\n" );
document.write( "Then  x+12 =  = {{(2/3)*30}}} = 20.\r\n" );
document.write( "\r\n" );
document.write( "Hence, x = 20-12 = 8.\r\n" );
document.write( "\r\n" );
document.write( "Answer.  8 workers must be added to 12 workers.\r\n" );
