\frac{10}{9}=\frac{x}{\pi }
Whakahekea te hautanga \frac{200}{180} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
\frac{x}{\pi }=\frac{10}{9}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{1}{\pi }x=\frac{10}{9}
He hanga arowhānui tō te whārite.
\frac{\frac{1}{\pi }x\pi }{1}=\frac{\frac{10}{9}\pi }{1}
Whakawehea ngā taha e rua ki te \pi ^{-1}.
x=\frac{\frac{10}{9}\pi }{1}
Mā te whakawehe ki te \pi ^{-1} ka wetekia te whakareanga ki te \pi ^{-1}.
x=\frac{10\pi }{9}
Whakawehe \frac{10}{9} ki te \pi ^{-1}.
