Tohaina
Kua tāruatia ki te papatopenga
k=\frac{11}{12}-\frac{7}{12}
Tangohia te \frac{7}{12} mai i ngā taha e rua.
k=\frac{11-7}{12}
Tā te mea he rite te tauraro o \frac{11}{12} me \frac{7}{12}, me tango rāua mā te tango i ō raua taurunga.
k=\frac{4}{12}
Tangohia te 7 i te 11, ka 4.
k=\frac{1}{3}
Whakahekea te hautanga \frac{4}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
