Kua tāruatia ki te papatopenga
9x=5.4+1.8
Me tāpiri te 1.8 ki ngā taha e rua.
9x=7.2
Tāpirihia te 5.4 ki te 1.8, ka 7.2.
x=\frac{7.2}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{72}{90}
Whakarohaina te \frac{7.2}{9} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{4}{5}
Whakahekea te hautanga \frac{72}{90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 18.
