Aromātai

$$\frac{92}{3}\approx 30.666666667$$

Ngā Upane Otinga

Whakareatia te 3 ki te 3, ka 9.

$$\frac{9+1}{3}\times \frac{9\times 5+1}{5}$$

Tāpirihia te 9 ki te 1, ka 10.

$$\frac{10}{3}\times \frac{9\times 5+1}{5}$$

Whakareatia te 9 ki te 5, ka 45.

$$\frac{10}{3}\times \frac{45+1}{5}$$

Tāpirihia te 45 ki te 1, ka 46.

$$\frac{10}{3}\times \frac{46}{5}$$

Me whakarea te \frac{10}{3} ki te \frac{46}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{10\times 46}{3\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{10\times 46}{3\times 5}.

$$\frac{460}{15}$$

Whakahekea te hautanga \frac{460}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{92}{3}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 23}{3} = 30\frac{2}{3} = 30.666666666666668$$
