document.write( "(1) In going from 10 men on the job to 15 men on the job, the number of men gets multiplied by 15/10 = 3/2/  Since more men means less time to do the job, that means the time required to do the job gets multiplied by 2/3.<br><BR>\n" );
document.write( "(2) In changing the number of cars from 2 to 9, the amount of time required to do the job gets multiplied by 9/2.<br><BR>\n" );
document.write( "So the 3 days it takes the 10 men to assemble 2 sports cars gets multiplied by 2/3 because of the increased number of workers and by 9/2 because of the increased number of sports cars:<br><BR>\n" );
