Yeah, it's crazy to see my dad at work in his shop - the amount of intuition he has of fractional measurements is insane, but he can do the math so quickly. In that specific context, if you were to do the math with decimal measurements it would take longer and leave you with some funky units. It's hard to describe how you work with the fractions - but the lumber and the saw blades and the screws and even the finishes all come in these standardized fractional increments that are easy to work with. And the skill required of a project is directly related to the precision of the measurement you go down to - 1/8, 1/16, 1/32, etc. It all just kinda works.
