Aromātai

$$\frac{78}{25}=3.12$$

Ngā Upane Otinga

Whakareatia te 1 ki te 5, ka 5.

$$\frac{5+1}{5}\times \frac{2\times 5+3}{5}$$

Tāpirihia te 5 ki te 1, ka 6.

$$\frac{6}{5}\times \frac{2\times 5+3}{5}$$

Whakareatia te 2 ki te 5, ka 10.

$$\frac{6}{5}\times \frac{10+3}{5}$$

Tāpirihia te 10 ki te 3, ka 13.

$$\frac{6}{5}\times \frac{13}{5}$$

Me whakarea te \frac{6}{5} ki te \frac{13}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{6\times 13}{5\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{6\times 13}{5\times 5}.

$$\frac{78}{25}$$

Tauwehe

$$\frac{2 \cdot 3 \cdot 13}{5 ^ {2}} = 3\frac{3}{25} = 3.12$$
