Ngā Upane Otinga

Me tahuri ki tau ā-ira 2.7 ki te hautau \frac{27}{10}.

$$\frac{1}{2}\times \frac{27}{10}\times 2.2$$

Me whakarea te \frac{1}{2} ki te \frac{27}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 27}{2\times 10}\times 2.2$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 27}{2\times 10}.

$$\frac{27}{20}\times 2.2$$

Me tahuri ki tau ā-ira 2.2 ki te hautau \frac{22}{10}. Whakahekea te hautanga \frac{22}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{27}{20}\times \frac{11}{5}$$

Me whakarea te \frac{27}{20} ki te \frac{11}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{27\times 11}{20\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{27\times 11}{20\times 5}.

$$\frac{297}{100}$$

Tauwehe

$$\frac{11 \cdot 3 ^ {3}}{2 ^ {2} \cdot 5 ^ {2}} = 2\frac{97}{100} = 2.97$$
