Whakaoti i te 9*10^9*x*0.004/3000=0.016

$$\frac { 9 \cdot 10 ^ { 9 } \cdot x \cdot 0.004 } { 3000 } = 0.016$$

Whakaoti mō x

$$x=\frac{1}{750000}\approx 0.000001333$$

Me whakarea ngā taha e rua ki te 3000.

$$9\times 10^{9}x\times 0.004=0.016\times 3000$$

Tātaihia te 10 mā te pū o 9, kia riro ko 1000000000.

$$9\times 1000000000x\times 0.004=0.016\times 3000$$

Whakareatia te 9 ki te 1000000000, ka 9000000000.

$$9000000000x\times 0.004=0.016\times 3000$$

Whakareatia te 9000000000 ki te 0.004, ka 36000000.

$$36000000x=0.016\times 3000$$

Whakareatia te 0.016 ki te 3000, ka 48.

$$36000000x=48$$

Whakawehea ngā taha e rua ki te 36000000.

$$x=\frac{48}{36000000}$$

Whakahekea te hautanga \frac{48}{36000000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 48.

$$x=\frac{1}{750000}$$
