Tohaina
Kua tāruatia ki te papatopenga
\frac{4}{0.25}=w-4.3
Whakawehea ngā taha e rua ki te 0.25.
\frac{400}{25}=w-4.3
Whakarohaina te \frac{4}{0.25} mā te whakarea i te taurunga me te tauraro ki te 100.
16=w-4.3
Whakawehea te 400 ki te 25, kia riro ko 16.
w-4.3=16
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
w=16+4.3
Me tāpiri te 4.3 ki ngā taha e rua.
w=20.3
Tāpirihia te 16 ki te 4.3, ka 20.3.
