Reply to Speeding Up Music Video To Fit Tempo / Speed Formula?

I've been getting into adding video to my mixes/bootlegs and I had a question about how to match them up.

If I have an original song at 125 BPM and needed to get the original song's video to match 128 BPM how would I figure out the percentage that I need to speed the video up? Im sure it's pretty simple but I can't work it out. Thanks for the help.
