Aromātai

$$\frac{23}{2}=11.5$$

Ngā Upane Otinga

Whakareatia te 6 ki te 4, ka 24.

$$\frac{24+1}{4}\times \frac{2\times 10+3}{10}\times \frac{4}{5}$$

Tāpirihia te 24 ki te 1, ka 25.

$$\frac{25}{4}\times \frac{2\times 10+3}{10}\times \frac{4}{5}$$

Whakareatia te 2 ki te 10, ka 20.

$$\frac{25}{4}\times \frac{20+3}{10}\times \frac{4}{5}$$

Tāpirihia te 20 ki te 3, ka 23.

$$\frac{25}{4}\times \frac{23}{10}\times \frac{4}{5}$$

Me whakarea te \frac{25}{4} ki te \frac{23}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25\times 23}{4\times 10}\times \frac{4}{5}$$

Mahia ngā whakarea i roto i te hautanga \frac{25\times 23}{4\times 10}.

$$\frac{575}{40}\times \frac{4}{5}$$

Whakahekea te hautanga \frac{575}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{115}{8}\times \frac{4}{5}$$

Me whakarea te \frac{115}{8} ki te \frac{4}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{115\times 4}{8\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{115\times 4}{8\times 5}.

$$\frac{460}{40}$$

Whakahekea te hautanga \frac{460}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$\frac{23}{2}$$

Tauwehe

$$\frac{23}{2} = 11\frac{1}{2} = 11.5$$
