\r\n" );
document.write( "The 3×5 photo's area is (3 in)×(5 in) = 15 in²\r\n" );
document.write( "The 5×7 photo's area is (5 in)×(7 in) = 35 in²\r\n" );
document.write( "\r\n" );
document.write( "To compare A to B, we divide A by B\r\n" );

document.write( "To compare 35 in² to 15 in² we divide 35 by 15.\r\n" );
document.write( "\r\n" );
document.write( "We do that and get that 35 in² is 2.333... times as many \r\n" );
document.write( "as 15 in².\r\n" );
document.write( "\r\n" );
document.write( "That's 1 + 1.333... so it's one times PLUS 1.333... times\r\n" );
document.write( "\r\n" );
document.write( "Answer: 1.333... times or 133.333% or % increase\r\n" );
