Whakaoti mō h
h = \frac{8}{5} = 1\frac{3}{5} = 1.6
Tohaina
Kua tāruatia ki te papatopenga
400\times 2=\left(145+355\right)h
Me whakarea ngā taha e rua ki te 2.
800=\left(145+355\right)h
Whakareatia te 400 ki te 2, ka 800.
800=500h
Tāpirihia te 145 ki te 355, ka 500.
500h=800
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
h=\frac{800}{500}
Whakawehea ngā taha e rua ki te 500.
h=\frac{8}{5}
Whakahekea te hautanga \frac{800}{500} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 100.
