\frac{x}{100}=\frac{8}{80}
Whakawehea ngā taha e rua ki te 80.
\frac{x}{100}=\frac{1}{10}
Whakahekea te hautanga \frac{8}{80} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
x=\frac{1}{10}\times 100
Me whakarea ngā taha e rua ki te 100.
x=\frac{100}{10}
Whakareatia te \frac{1}{10} ki te 100, ka \frac{100}{10}.
x=10
Whakawehea te 100 ki te 10, kia riro ko 10.
