Morphology
The phrase is a straightforward adjective+noun composition: 'irrational' specifies a property of the noun 'number', so a learner who knows 'irrational' as 'not writable as a fraction' will directly infer 'a number that cannot be expressed as a ratio of two integers'. This follows a standard, cross-linguistic grammatical pattern (adjective modifying noun) and is therefore transparently interpretable from its constituents.
Etymology
Irrational number comes from a famous Greek story where a thinker found that the diagonal of a square could not be written as a simple fraction, and people were surprised. So irrational number means a number that 'cannot be written as a simple fraction'.
