Kua tāruatia ki te papatopenga
3\times 9x=0.9\times 3
Me whakarea ngā taha e rua ki te 3.
9x=0.9
Me whakakore te 3 ki ngā taha e rua.
x=\frac{0.9}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{9}{90}
Whakarohaina te \frac{0.9}{9} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{1}{10}
Whakahekea te hautanga \frac{9}{90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.
