Tohaina
Kua tāruatia ki te papatopenga
0.5w=4.5+1.5
Me tāpiri te 1.5 ki ngā taha e rua.
0.5w=6
Tāpirihia te 4.5 ki te 1.5, ka 6.
w=\frac{6}{0.5}
Whakawehea ngā taha e rua ki te 0.5.
w=\frac{60}{5}
Whakarohaina te \frac{6}{0.5} mā te whakarea i te taurunga me te tauraro ki te 10.
w=12
Whakawehea te 60 ki te 5, kia riro ko 12.
