document.write( "The record  A:B:C = 10:12:15 means, by definition, that there is a quantity x such that A = 10x, B = 12x, C = 15x,\r\n" );

document.write( "and this quantity \"x\" is called  \"a common measure\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, in our case, that means that the common measure is 220 Hz = 10x; hence, x =  = 22 Hz.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then other two notes are 12*22 = 264 Hz  and  15*22 = 330 Hz.\r\n" );
