Of course, if you use "fractions" then, we agree, no error will be introduced nor accumulated over computations which is better. The code base I'm talking about is Java 10 years ago. I was not aware of fractions at that time. There was only BigDecimal which was painful to work with (the reason why we ditched it at the time).

It's mostly painful because Java doesn't allow custom types to use operators, which I think was a maybe reasonable principle applied way too strictly. The same applies to any Fraction type you'd implement in Java.

Still, I'll take "verbose" over "error-prone and possibly wrong".
