Whakaoti mō b
b=\frac{A}{4}
Whakaoti mō A
A=4b
Tohaina
Kua tāruatia ki te papatopenga
4b=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{4b}{4}=\frac{A}{4}
Whakawehea ngā taha e rua ki te 4.
b=\frac{A}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
