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

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

Whakaoti mō x

$$x=\frac{1}{2500}=0.0004$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

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

Whakareatia te 2 ki te 100000, ka 200000.

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

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

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

Whakareatia te 2 ki te 10, ka 20.

$$\frac{1}{125}=20x$$

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

$$20x=\frac{1}{125}$$

Whakawehea ngā taha e rua ki te 20.

$$x=\frac{\frac{1}{125}}{20}$$

Tuhia te \frac{\frac{1}{125}}{20} hei hautanga kotahi.

$$x=\frac{1}{125\times 20}$$

Whakareatia te 125 ki te 20, ka 2500.

$$x=\frac{1}{2500}$$
