You need to wrap your code in <code> and </code> tags. The characters [ and ] are special to perl monks and can't put put as literal text in your post. You should also use <p> and </p> tags around paragraphs.
A general tip is to put
use strict;
use warnings;
at the start of every script you write until you know what you are doing. They wil pick up typos and dubious practices.
Assuming I've understood your problem then this does what you want.
my @data = get_data(); # or however you get them
my %count;
foreach my $datum (@data) {
++$count{$datum};
};
foreach my $item_count ( values %count ) {
$item_count *= 100/@data;
}
Now %count will have a key/value for each datum and its frequency as a percentage.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
