The decimal place stays where it is and the numbers moves to the left 5 times. You have to use zeros as place holders. When people say "put zeros on the end" they are very wrong!!!!!!

Consider #0.25 xx 10#.

If you put a zero on the end you get: #0.250# which is no different in value.

Move the number 1 place to the left however and you get #2.5# which is correct.
