Ngā Upane Otinga

Ka taea te hautanga \frac{-2}{3} te tuhi anō ko -\frac{2}{3} mā te tango i te tohu tōraro.

$$-\frac{2}{3}\times \frac{-8}{14}\times \frac{7}{10}$$

Whakahekea te hautanga \frac{-8}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{2}{3}\left(-\frac{4}{7}\right)\times \frac{7}{10}$$

Me whakarea te -\frac{2}{3} ki te -\frac{4}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-2\left(-4\right)}{3\times 7}\times \frac{7}{10}$$

Mahia ngā whakarea i roto i te hautanga \frac{-2\left(-4\right)}{3\times 7}.

$$\frac{8}{21}\times \frac{7}{10}$$

Me whakarea te \frac{8}{21} ki te \frac{7}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{8\times 7}{21\times 10}$$

Mahia ngā whakarea i roto i te hautanga \frac{8\times 7}{21\times 10}.

$$\frac{56}{210}$$

Whakahekea te hautanga \frac{56}{210} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 14.

$$\frac{4}{15}$$
