Tohaina
Kua tāruatia ki te papatopenga
0.4b=2+2
Me tāpiri te 2 ki ngā taha e rua.
0.4b=4
Tāpirihia te 2 ki te 2, ka 4.
b=\frac{4}{0.4}
Whakawehea ngā taha e rua ki te 0.4.
b=\frac{40}{4}
Whakarohaina te \frac{4}{0.4} mā te whakarea i te taurunga me te tauraro ki te 10.
b=10
Whakawehea te 40 ki te 4, kia riro ko 10.
