Kua tāruatia ki te papatopenga
\frac{12}{15}=z-\frac{1}{5}
Whakawehea ngā taha e rua ki te 15.
\frac{4}{5}=z-\frac{1}{5}
Whakahekea te hautanga \frac{12}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
z-\frac{1}{5}=\frac{4}{5}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
z=\frac{4}{5}+\frac{1}{5}
Me tāpiri te \frac{1}{5} ki ngā taha e rua.
z=\frac{4+1}{5}
Tā te mea he rite te tauraro o \frac{4}{5} me \frac{1}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
z=\frac{5}{5}
Tāpirihia te 4 ki te 1, ka 5.
z=1
Whakawehea te 5 ki te 5, kia riro ko 1.
