Hi, congratulations on your new tablet and welcome to the forum. Nice to have you as a member of Android Tablets. Assuming the problem is with tablet internal memory, try moving all the media files (books, pictures, videos, movies, music files etc.) that you can to the SD card. If RAM is the problem, try a RAM cleaner like Clean Master ( https://play.google.com/store/apps/details?id=com.cleanmaster.mguard ).
