What portion of a video file is audio information? I have a large number of m2t video files where the audio is worthless to me. I'm curious if removing the audio portion from these files will notably decrease the file size. Could someone give me a ballpark estimate of how much this will decrease file size? For example, how much will a 5 GB m2t video file be reduced?

To get the average proportions of the audio stream, just check a few of your videos and calculate ...

There are variables you don't mention, but you can make a quick estimate based on the video bit rate and the audio bit rate. With (say) 4800Kb/s video and 48Kb/s audio, the audio represents 1% of the file.
