Whakahekea te hautanga \frac{80}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$\frac{\frac{1000\times \frac{4}{5}}{164}\times 0\times 38}{100}\times 80-80\times 1000$$

Tuhia te 1000\times \frac{4}{5} hei hautanga kotahi.

$$\frac{\frac{\frac{1000\times 4}{5}}{164}\times 0\times 38}{100}\times 80-80\times 1000$$

Whakareatia te 1000 ki te 4, ka 4000.

$$\frac{\frac{\frac{4000}{5}}{164}\times 0\times 38}{100}\times 80-80\times 1000$$

Whakawehea te 4000 ki te 5, kia riro ko 800.

$$\frac{\frac{800}{164}\times 0\times 38}{100}\times 80-80\times 1000$$

Whakahekea te hautanga \frac{800}{164} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{\frac{200}{41}\times 0\times 38}{100}\times 80-80\times 1000$$

$$\frac{0\times 38}{100}\times 80-80\times 1000$$

Whakareatia te 0 ki te 38, ka 0.

$$\frac{0}{100}\times 80-80\times 1000$$

Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.

$$0\times 80-80\times 1000$$

Whakareatia te 0 ki te 80, ka 0.

$$0-80\times 1000$$
