Tohaina
Kua tāruatia ki te papatopenga
6E=14.4\times 12
Me whakarea ngā taha e rua ki te 12.
6E=172.8
Whakareatia te 14.4 ki te 12, ka 172.8.
E=\frac{172.8}{6}
Whakawehea ngā taha e rua ki te 6.
E=\frac{1728}{60}
Whakarohaina te \frac{172.8}{6} mā te whakarea i te taurunga me te tauraro ki te 10.
E=\frac{144}{5}
Whakahekea te hautanga \frac{1728}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
