Yeah, either Decimal becomes default or 13/10 is a fraction. If
Decimal becomes default, we could have Decimal(13 / 10) = Decimal(13)
/ Decimal(10). We would have "expected" results.

If Decimals are default, Fractions can have a .divide() method which
returns Decimal(Numerator) / Decimal(Denominator), which is used when
Fractions and Decimals are mixed.
