Ngā Upane Otinga

Tātaihia te 7.9 mā te pū o 2, kia riro ko 62.41.

$$62.41\times \frac{1}{5}$$

Me tahuri ki tau ā-ira 62.41 ki te hautau \frac{6241}{100}.

$$\frac{6241}{100}\times \frac{1}{5}$$

Me whakarea te \frac{6241}{100} ki te \frac{1}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{6241\times 1}{100\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{6241\times 1}{100\times 5}.

$$\frac{6241}{500}$$

Tauwehe

$$\frac{79 ^ {2}}{2 ^ {2} \cdot 5 ^ {3}} = 12\frac{241}{500} = 12.482$$
