Kua tāruatia ki te papatopenga
\frac{x}{10}=\frac{16}{40}
Whakawehea ngā taha e rua ki te 40.
\frac{x}{10}=\frac{2}{5}
Whakahekea te hautanga \frac{16}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
x=\frac{2}{5}\times 10
Me whakarea ngā taha e rua ki te 10.
x=\frac{2\times 10}{5}
Tuhia te \frac{2}{5}\times 10 hei hautanga kotahi.
x=\frac{20}{5}
Whakareatia te 2 ki te 10, ka 20.
x=4
Whakawehea te 20 ki te 5, kia riro ko 4.
