Ngā Upane Otinga

Tātaihia te 10 mā te pū o 7, kia riro ko 10000000.

$$\frac{\left(1.5\times 10000000-3\times 10^{6}\right)\times 0.03}{3.9\times 10^{7}}$$

Whakareatia te 1.5 ki te 10000000, ka 15000000.

$$\frac{\left(15000000-3\times 10^{6}\right)\times 0.03}{3.9\times 10^{7}}$$

Tātaihia te 10 mā te pū o 6, kia riro ko 1000000.

$$\frac{\left(15000000-3\times 1000000\right)\times 0.03}{3.9\times 10^{7}}$$

Whakareatia te 3 ki te 1000000, ka 3000000.

$$\frac{\left(15000000-3000000\right)\times 0.03}{3.9\times 10^{7}}$$

Tangohia te 3000000 i te 15000000, ka 12000000.

$$\frac{12000000\times 0.03}{3.9\times 10^{7}}$$

Whakareatia te 12000000 ki te 0.03, ka 360000.

$$\frac{360000}{3.9\times 10^{7}}$$

Tātaihia te 10 mā te pū o 7, kia riro ko 10000000.

$$\frac{360000}{3.9\times 10000000}$$

Whakareatia te 3.9 ki te 10000000, ka 39000000.

$$\frac{360000}{39000000}$$

Whakahekea te hautanga \frac{360000}{39000000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 120000.
