Tohaina
Kua tāruatia ki te papatopenga
50=K\times 900
Tātaihia te 30 mā te pū o 2, kia riro ko 900.
K\times 900=50
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
K=\frac{50}{900}
Whakawehea ngā taha e rua ki te 900.
K=\frac{1}{18}
Whakahekea te hautanga \frac{50}{900} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 50.
