Ngā Upane Otinga

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

$$\frac{0.5\times 9.8}{14\times 10^{1}}$$

Whakareatia te 0.5 ki te 9.8, ka 4.9.

$$\frac{4.9}{14\times 10^{1}}$$

Tātaihia te 10 mā te pū o 1, kia riro ko 10.

$$\frac{4.9}{14\times 10}$$

Whakareatia te 14 ki te 10, ka 140.

$$\frac{4.9}{140}$$

Whakarohaina te \frac{4.9}{140} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{49}{1400}$$

Whakahekea te hautanga \frac{49}{1400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$\frac{7}{200}$$

Tauwehe

$$\frac{7}{2 ^ {3} \cdot 5 ^ {2}} = 0.035$$
