\"10 men can paint 30 houses in 60 days and 5 men can paint 15 house in how many days\"
\n" ); document.write( "
\r\n" );
document.write( "There are several ways to get to the answer.  The simplest way here\r\n" );
document.write( "is that for half the workers to paint half the number of houses would \r\n" );
document.write( "take the same amout of time, which is 60 days.\r\n" );
document.write( "\r\n" );
document.write( "------------------------------------\r\n" );
document.write( "\r\n" );
document.write( "Or here's another way:\r\n" );
document.write( "\r\n" );
document.write( "10 men can paint 30 houses in 60 days,\r\n" );
document.write( "\r\n" );
document.write( "therefore 1 man can paint 3 houses in 60 days;\r\n" );
document.write( "\r\n" );
document.write( "therefore 1 man can paint 15 houses in 300 days;\r\n" );
document.write( "\r\n" );
document.write( "therefore 5 men can paint 15 houses in 60 days.\r\n" );
document.write( "\r\n" );
document.write( "--------------------------------\r\n" );
document.write( "\r\n" );
document.write( "Still another way is to use the worker-jobs-time formula\r\n" );
document.write( "\r\n" );
document.write( "W1 = number of workers in the first situation\r\n" );
document.write( "T1 = time required in the first situation\r\n" );
document.write( "J1 = number of jobs done in the first situation\r\n" );
document.write( "\r\n" );
document.write( "W2 = number of workers in the second situation\r\n" );
document.write( "T2 = time required in the second situation\r\n" );
document.write( "J2 = number of jobs done in the second situation\r\n" );
document.write( "\r\n" );
document.write( "The formula is\r\n" );
document.write( "\r\n" );
document.write( "\"%28W%5B1%5D%2AT%5B1%5D%29%2FJ%5B1%5D=+%28W%5B2%5D%2AT%5B2%5D%29%2FJ%5B2%5D+\"\r\n" );
