Ngā Upane Otinga

Hei whakawehe i ngā pū o te pūtake kotahi, tangohia te taupū o te taurunga i te taupū o te tauraro.

$$\frac{205}{4\times 10^{6}}$$

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

$$\frac{205}{4\times 1000000}$$

Whakareatia te 4 ki te 1000000, ka 4000000.

$$\frac{205}{4000000}$$

Whakahekea te hautanga \frac{205}{4000000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{41}{800000}$$

Tauwehe

$$\frac{41}{2 ^ {8} \cdot 5 ^ {5}} = 5.124999999999999 \times 10^{-5}$$
