[ -25/27x = -25/(27x) ] is the valid statement.

Another one...
Where are you coming from guys? From a wood?
-25/27x = -25/(27x) is correct.
1) Try this PHP code if you want:
<?php
$x = 54; // some sample value
echo -25/27*$x . " = " . (-25/27)*$x;
?>
You will be surprised when you'll see the result because it will be "-50 = -50"
2) Don't have PHP at your server? Ok, I believe you are able to do this:
a) click at
http://instacalc.com/
b) copy-paste this into the calculator's box: -25/27*54
c) remember the result (it will be -50)
d) copy-paste this into the calculator's box: -(25/27)*54
e) remember the result (it will be -50)
f) now compare the results you got in (c) and (e). aren't they equal?
(-25/27)x is baddog meant and it IS what he wrote. because:
(-25/27)*x = -25/27*x (note 2 ways to check it above)
PERIOD.
P.S.
x = 54 in both samples and
it does not belong to {-1, 0, 1} as you stated above.
