It can and sometimes is, but most the time cancellations are done easier in fraction form. It kind of depends on how the numbers work out, if you know you've got an easy cancellation in fraction you go with the fraction, if the decimal place is easier then they go with that. I don't do anything with relativistic speeds so it's just academic knowledge to me. I work with sound physics more than anything. The harmonic series is easiest to express in ratios and technically Hz is also an SI unit so we really do the same thing with sound. I don't really care what the actual Hz is most of the time, I just care that the root is 1 and know the divisors of the harmonics. Most the time plugging in the actual frequency to the math is rather pointless in the world of audio engineering, mostly we point lasers at mirrors or use a computer program and a high sensitivity directional microphone to tell us where to put what kind of baffling in a room.

I think we learned fractions for one semester in grade five or six. It annoys me when I have to deal with them.
