How to fix URL duplications

I would recommend setting up 301 redirects on duplicates and redirect them to their new URLs. You need to create the new pages first, then redirect the old URLs to the new pages. You can do this in Wordpress, for example, using a plugin called "Redirection" among other plugins that do similar things. You can find all the duplicate links in your Moz Crawl Diagnostics. I don't know much about RapidTables.com but it looks like all it does is give you the code you then need to add into your website. There are probably many solutions just like this out there, it really just depends on how you have your site set up and the resources you have available to you in terms of developers, etc.

I would recommend redirecting them also, but one thing I wouldn't recommend is using htacess to redirect them. If you are redirecting 9k urls you are going to feel a speed impact across your whole site if you use the htaccess to re-direct the urls. Put the redirects in your httpd.con file and it will keep things speedy since it does not load per site access. It usually sits in memory just waiting.
Also, I have to ask, are you duplicates caused by url strings or are they genuine duplicates? By url string I mean, site.com/page.php, site.com/page.php?variable=dog site.com/page.php?variable=cat. and so on. If that is the case you can just start redirecting any variable if you do not actually need them.
Also one thing you need to consider is adding a canonical tag to the pages, so while you are working on things search engines know what is the original link worthy content.
