\n" ); document.write( "a = \"1%2F6\"a + \"1%2F12\"a + \"1%2F7\"a + 5 + \"1%2F2\"a + 4
\n" ); document.write( "Multiply by the LCM (7 * 12 = 84), results:
\n" ); document.write( "84a = 14a + 7a + 12a + 84(5) + 42a + 84(4)
\n" ); document.write( "84a = 75a + 420 + 336
\n" ); document.write( "84a - 75a = 756
\n" ); document.write( "9a = 756
\n" ); document.write( "a = 756/9
\n" ); document.write( "a = 84 yrs grandpa's age when he made his final journey
