Morphology

improper + fraction

The noun is compositionally built from 'improper' + 'fraction', so a learner will infer it denotes a fraction that is somehow 'not proper' or 'unusual'. However, the precise mathematical criterion (numerator equal to or greater than the denominator) is a technical definition that is not directly predictable from the everyday meaning of 'improper', so full understanding typically requires prior exposure or instruction.

Etymology

The term improper fraction describes a fraction where the top number, the numerator, is equal to or larger than the bottom number, the denominator. Because it is not a 'proper' part less than one, the word 'improper' shows the fraction is one or more, so the name means a fraction with a numerator equal to or greater than the denominator.
