You can put SOME apps in the SD. You can't put every app in your SD. Try going to Configuration, Manage Applications, and change default data storage to your SD card.
After that, you'll still have your internal memory full, to make some space in the internal storage, go to downloaded applications and select every non Google App and then select move to SD (If it's allowed). Probably, the app will still be on the internal storage, but some of the data may migrate to the SD card.
If the space you made is not enough, then uninstall the actualizations of the preset google apps you don't use and deactivate them.
