Aromātai

$$0.2$$

Ngā Upane Otinga

Whakareatia te 1 ki te 25, ka 25.

$$1.25\times \frac{25+1}{25}\times \frac{2}{13}$$

Tāpirihia te 25 ki te 1, ka 26.

$$1.25\times \frac{26}{25}\times \frac{2}{13}$$

Me tahuri ki tau ā-ira 1.25 ki te hautau \frac{125}{100}. Whakahekea te hautanga \frac{125}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{5}{4}\times \frac{26}{25}\times \frac{2}{13}$$

Me whakarea te \frac{5}{4} ki te \frac{26}{25} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{5\times 26}{4\times 25}\times \frac{2}{13}$$

Mahia ngā whakarea i roto i te hautanga \frac{5\times 26}{4\times 25}.

$$\frac{130}{100}\times \frac{2}{13}$$

Whakahekea te hautanga \frac{130}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$\frac{13}{10}\times \frac{2}{13}$$

Me whakarea te \frac{13}{10} ki te \frac{2}{13} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{13\times 2}{10\times 13}$$

Me whakakore tahi te 13 i te taurunga me te tauraro.

$$\frac{2}{10}$$

Whakahekea te hautanga \frac{2}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{5}$$

Tauwehe

$$\frac{1}{5} = 0.2$$
