Tohaina
Kua tāruatia ki te papatopenga
2.2x=0.15+4
Me tāpiri te 4 ki ngā taha e rua.
2.2x=4.15
Tāpirihia te 0.15 ki te 4, ka 4.15.
x=\frac{4.15}{2.2}
Whakawehea ngā taha e rua ki te 2.2.
x=\frac{415}{220}
Whakarohaina te \frac{4.15}{2.2} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{83}{44}
Whakahekea te hautanga \frac{415}{220} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
