Morphology
The noun phrase is a straightforward adjective + noun composition: 'complex' (complicated, consisting of intricate parts) modifies 'fraction' (a numerator/denominator number), so the meaning — a more complicated fraction, typically one whose numerator or denominator contains fractions — is directly inferable from the parts. This compositional pattern is common cross-linguistically and follows normal English noun modification, so a B1 learner who knows both words will understand the MWE's basic sense.
Etymology
Complex fraction is a name for a fraction that has smaller fractions inside its numerator or denominator, like a big fraction with little fractions sitting on top or below it. So the word 'complex' points to those extra fractions, and that is why you usually change it into one simple 'fraction' to work with it.
