Tohaina
Kua tāruatia ki te papatopenga
140=k\times 2500
Tātaihia te 50 mā te pū o 2, kia riro ko 2500.
k\times 2500=140
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
k=\frac{140}{2500}
Whakawehea ngā taha e rua ki te 2500.
k=\frac{7}{125}
Whakahekea te hautanga \frac{140}{2500} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
