I have outlets that aren't grounded (only 2 prong) and I'm plugging in appliances that have 3 prongs. I have adaptors but am not sure of the easiest way to ground them. Could someone help with how to ground the adaptors? thanks.

You can't ground the adaptors. You'll need to see if you can change the 2 prong receptacles to 3 prong receptacles. To do this you will need a voltage tester. Take a reading from the hot (black) wire to the metal box. If you get a reading of 120 volts or a light using a neon bulb tester, then that indicates the box is grounded.
If the box is grounded then you can install a self-grounding 3 prong receptacle. If the box is not grounded then you can install a GFCI receptacle to replace the 2 prong. This will allow you to plug in a 3 prong plug, but you will still not have a ground. Those are your only choices.
Here's a link that'll detail all of this for you.
