Evaluate the expression.\r\n" );
document.write( "- 5/6 * ( - 9/10 ) divided by 17/20 \r\n" );
document.write( "\r\n" );
document.write( "÷\r\n" );
document.write( "\r\n" );
document.write( "We do the multiplication first because it's\r\n" );
document.write( "the first of the highest level of operation\r\n" );
document.write( "that appears. It is a negative multiplied by\r\n" );
document.write( "a negative, so we know the answer will be\r\n" );
document.write( "positive so we just write\r\n" );
document.write( "÷\r\n" );
document.write( "\r\n" );
document.write( "We can cancel the 5 into the 10 and write 1\r\n" );
document.write( "where we had 5 and 2 where we had 10:\r\n" );
document.write( "\r\n" );
document.write( "÷\r\n" );
document.write( "\r\n" );
document.write( "We can also cancel the 6 and the 9 by \r\n" );
document.write( "dividing both by 3 and putting 3 where\r\n" );
document.write( "we had 9 and 2 where we had 6\r\n" );
document.write( "\r\n" );
document.write( "÷\r\n" );
document.write( " \r\n" );
document.write( "Now multiply numerators 1·3 = 3 and \r\n" );
document.write( "denominators 2·2 = 4 and we have\r\n" );
document.write( "\r\n" );
document.write( "÷\r\n" );
document.write( "\r\n" );
document.write( "Invert the second fraction and change\r\n" );
document.write( "division to multiplication:\r\n" );
document.write( "\r\n" );
document.write( "×\r\n" );
document.write( "\r\n" );
document.write( "We can now cancel the 20 and the 4 \r\n" );
document.write( "by dividing both by 4 and putting 5\r\n" );
document.write( "where we had 20 and 1 where we had 4.\r\n" );
document.write( "\r\n" );
document.write( "×\r\n" );
document.write( "\r\n" );
document.write( "Finally we multiply numerators\r\n" );
document.write( "3·5 getting 15, and multiply\r\n" );
document.write( "denominators 1·17 = 17, and so\r\n" );
document.write( "the final answer is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
