Whakaoti i te 1600/10^5*2=10^4*2x

$$\frac { 1600 } { 10 ^ { 5 } \times 2 } = 10 ^ { 4 } \times 2 x$$

Whakaoti mō x

$$x=\frac{1}{2500000}=0.0000004$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 10 mā te pū o 5, kia riro ko 100000.

$$\frac{1600}{100000\times 2}=10^{4}\times 2x$$

Whakareatia te 100000 ki te 2, ka 200000.

$$\frac{1600}{200000}=10^{4}\times 2x$$

Whakahekea te hautanga \frac{1600}{200000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 1600.

$$\frac{1}{125}=10^{4}\times 2x$$

Tātaihia te 10 mā te pū o 4, kia riro ko 10000.

$$\frac{1}{125}=10000\times 2x$$

Whakareatia te 10000 ki te 2, ka 20000.

$$\frac{1}{125}=20000x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$20000x=\frac{1}{125}$$

Whakawehea ngā taha e rua ki te 20000.

$$x=\frac{\frac{1}{125}}{20000}$$

Tuhia te \frac{\frac{1}{125}}{20000} hei hautanga kotahi.

$$x=\frac{1}{125\times 20000}$$

Whakareatia te 125 ki te 20000, ka 2500000.

$$x=\frac{1}{2500000}$$
