> Telugu (a language of southern India) has an interesting traditional numeric system: base ten for integers, and base four for fractions.

If they do consistently that is not too bad. Compare that with imperial units, which, depending on the quantity and sometimes its magnitude, uses

- base 10 for integers and base 12 for fractions (lengths in feet and inches). Alternatively, base 10 for mikes, base 5,280 for feet’s in a mile, base 12 for inches in a foot.

- base 10 for integers and base 14 for fractions (weights in stone and pound). Alternatively, there’s a base 112 when measuring in long tons and stones or 1,016 when using long tons and pounds)

- base 10 for integers and base 4 for fractions (lengths in miles and quarter/half miles)

And that’s ignoring specific units for weighing gold, diamonds, etc.
