Ninu imo Mathematiki, nomba oniipin (rational number) ni nomba ti a le ko le gege be ipin nọ́mbà odidi meji. Nomba bi $\tfrac ab$, to je pe b ki se odo.

A le ko awon nomba oniipin ni opolopo ona, fun apere $\tfrac 36=\tfrac 24=\tfrac 12$, sugbon o d'ero julo nigbati a ati b ko ba ni nomba kanna ti a le fi pin won a fi 1.
