\r\n" );
document.write( "A teacher is 15 years older than her student, who is\r\n" );
document.write( ", and thus the teacher is . In 15 years, the\r\n" );
document.write( "ratio of their ages will be 3:2, because the teacher will be\r\n" );
document.write( " and the student will be , and the fraction\r\n" );
document.write( " equals to the fraction  .\r\n" );
document.write( "\r\n" );
document.write( "How'd I get that?  By using the same words as I did above,\r\n" );
document.write( "only using  for the student's age instead of .\r\n" );
document.write( "\r\n" );
document.write( "A teacher is 15 years older than her student, who is ,\r\n" );
document.write( "and thus the teacher is . In 15 years, the ratio of\r\n" );
document.write( "their ages will be 3:2, because the teacher will be\r\n" );
document.write( " and the student will be , and the\r\n" );
document.write( "fraction  equals to the fraction .\r\n" );
document.write( "\r\n" );
document.write( "So the equation is:\r\n" );
document.write( "\r\n" );
document.write( " = \r\n" );
document.write( "\r\n" );
document.write( "Solve that and get X = 15, and so the teacher is 30.\r\n" );
