\n" ); document.write( "Jay can do a painting job in 2/3 as many days as Chris can,
\n" ); document.write( "and Chris can do it in 3/4 as many days as Araceli can.
\n" ); document.write( "If all three work together, they can do it in 36/13 days.
\n" ); document.write( "In how many days can each of them alone do the work?
\n" ); document.write( "~~~~~~~~~~~~~~\r

\r\n" );
document.write( "Let \"a\" be the Araceli's rate of work.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then Chris' rate of work is  \"%284%2F3%29a\", and Jay's rate of work is \"%283%2F2%29a\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Their combined rate of work is then \r\n" );
document.write( "\r\n" );
document.write( "    a + \"%284%2F3%29a\" + \"%283%2F2%29%2A%284%2F3%29a\" = a + \"%284%2F3%29a\" + 2a = \"%283a+%2B+4a+%2B+6a%29%2F3\" = \"%2813%2F3%29a\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the other side, their combined rate of work is  \"13%2F36\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It gives us this equation\r\n" );
document.write( "\r\n" );
document.write( "    \"%2813%2F3%29a\" = \"13%2F36\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this equation,  a = \"1%2F12\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus Araceli can make the job in 12 days, working alone; Cris can make it in  \"%283%2F4%29%2A12\" = 9 days\r\n" );
document.write( "and Jay can make it in  \"%282%2F3%29%2A9\" = 6 days.    ANSWER\r\n" );
