Kua tāruatia ki te papatopenga
0.25w=8.75-6.5
Tangohia te 6.5 mai i ngā taha e rua.
0.25w=2.25
Tangohia te 6.5 i te 8.75, ka 2.25.
w=\frac{2.25}{0.25}
Whakawehea ngā taha e rua ki te 0.25.
w=\frac{225}{25}
Whakarohaina te \frac{2.25}{0.25} mā te whakarea i te taurunga me te tauraro ki te 100.
w=9
Whakawehea te 225 ki te 25, kia riro ko 9.
