I'm a newbe so be nice
Looking in the menu of my D3100 I can't find a setting for shooting ratios. Is the default 3:2 or 4:3? Is it possible to choose one or the other?
Also, to print a 4x6 should I use 3:2 or 4:3? Which one would be best for printing 5x7 and 8x10 with the least cropping?

Not many cameras and especially dSLRs let you change the aspect ratio of the captured image. Some FX (full frame) Nikon dSLRs will in camera crop from the FX (36 × 23.9 mm or 1.5062) to the DX (23.1 × 15.4 mm or 1.5) when a DX lens is attached to the camera. But even with a the automatic crop, the aspect ratio is almost the same.
As to printing, you need to crop the image in post processing, a process very similar to how 35mm film users cropped in the dark room during the enalarging process. This means when you compose your image, you need to allow enough additional content within in the viewfinder to allow for the necessary cropping when printing. There are some viewfinder screens that include crop lines for 5x 7 or 8x10, but these screens require replacement of the viewfinder screen for the different crops.

Your camera's aspect ratio is fixed, and it is 3:2. Any prints that are the same ratio, such as 4 x 6, 8 x 12, etc., do not have to be cropped unless you are trying to eliminate a part of the image. If you want 8 x 10 prints or some other aspect ratio, you will have to crop. 5 x 7 would give you the least crop, 4 x 6, of course, no crop needed.

Exactly the information I was looking for.
Thanks to both of you for replying with such good information. This is really a good forum for people who are new to digital photography.
Although I just bought a D3100, my first and only other camera is a Canon "AE-1 Program" bought new in 1981/82.
