Whakahekea te hautanga \frac{100}{360} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
4\times \frac{\sqrt{5}}{\sqrt{18}}
Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{5}{18}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{5}}{\sqrt{18}}.
4\times \frac{\sqrt{5}}{3\sqrt{2}}
Tauwehea te 18=3^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{3^{2}\times 2} hei hua o ngā pūtake rua \sqrt{3^{2}}\sqrt{2}. Tuhia te pūtakerua o te 3^{2}.
