Whakaoti i te 16000/2*10^5=2*x*10^11

$$\frac{ 16000 }{ 2 \times { 10 }^{ 5 } } =2 \times x \times { 10 }^{ 11 }$$

Whakaoti mō x

$$x=\frac{1}{2500000000000}=4 \cdot 10^{-13}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$\frac{16000}{2\times 100000}=2x\times 10^{11}$$

Whakareatia te 2 ki te 100000, ka 200000.

$$\frac{16000}{200000}=2x\times 10^{11}$$

Whakahekea te hautanga \frac{16000}{200000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8000.

$$\frac{2}{25}=2x\times 10^{11}$$

Tātaihia te 10 mā te pū o 11, kia riro ko 100000000000.

$$\frac{2}{25}=2x\times 100000000000$$

Whakareatia te 2 ki te 100000000000, ka 200000000000.

$$\frac{2}{25}=200000000000x$$

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

$$200000000000x=\frac{2}{25}$$

Whakawehea ngā taha e rua ki te 200000000000.

$$x=\frac{\frac{2}{25}}{200000000000}$$

Tuhia te \frac{\frac{2}{25}}{200000000000} hei hautanga kotahi.

$$x=\frac{2}{25\times 200000000000}$$

Whakareatia te 25 ki te 200000000000, ka 5000000000000.

$$x=\frac{2}{5000000000000}$$

Whakahekea te hautanga \frac{2}{5000000000000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{1}{2500000000000}$$
