Morphology

rational = ratio (opaque) = ratio + al

The adjective is historically related to Latin ratio 'reason/account', but that connection is not obvious from modern English 'ratio', so the meaning is not easily recoverable.

Etymology

Rational comes from the Latin root ratio, which means 'reason' or 'calculation', so to be rational is to use reason and careful thought rather than emotion.
