Whakaoti mō W
W=\frac{A}{8}
Whakaoti mō A
A=8W
Tohaina
Kua tāruatia ki te papatopenga
8W=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{8W}{8}=\frac{A}{8}
Whakawehea ngā taha e rua ki te 8.
W=\frac{A}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
