Kua tāruatia ki te papatopenga
\frac{2}{9}\times 3=x
Me whakarea ngā taha e rua ki te 3.
\frac{2\times 3}{9}=x
Tuhia te \frac{2}{9}\times 3 hei hautanga kotahi.
\frac{6}{9}=x
Whakareatia te 2 ki te 3, ka 6.
\frac{2}{3}=x
Whakahekea te hautanga \frac{6}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
x=\frac{2}{3}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
