In practice you would just use decimal inches. Doesn’t really make it better but you can machine something without ever seeing a fraction if you want to since everything will be in thousandths of an inch.
Maybe in your particular industry, but I reckon most people using imperial units aren’t using measuring devices with decimal inches or needing the precision of .0001"
most electronics breadboards and the pins from (non-tiny) microchips / ICs are spaced at 2.54mm apart, which i eventually realised is a tenth of an inch.

Decimal inches?

hey none of that mathematics witchery here dude. we guesstimate or we do nothing (and i’m too tired to guess)
