Tohaina
Kua tāruatia ki te papatopenga
850=c\times 8000
Tātaihia te 20 mā te pū o 3, kia riro ko 8000.
c\times 8000=850
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
c=\frac{850}{8000}
Whakawehea ngā taha e rua ki te 8000.
c=\frac{17}{160}
Whakahekea te hautanga \frac{850}{8000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 50.
