PQRST9875 = PQRST0000 + 9875.\r
\n" ); document.write( "\n" ); document.write( "Now \"%28PQRST9875%29%2F625+=+%28PQRST0000%29%2F625+%2B+9875%2F625\".
\n" ); document.write( "==> PQRST0000/625 is a positive integer, whereas 9875/625 = 79/5 in lowest terms. Hence \"%28PQRST9875%29%2F625\" is not a positive integer.
