Ngā Upane Otinga

Ka taea te hautanga \frac{-2}{7} te tuhi anō ko -\frac{2}{7} mā te tango i te tohu tōraro.

$$-\frac{2}{7}+\frac{1}{3}\times \frac{6}{11}$$

Me whakarea te \frac{1}{3} ki te \frac{6}{11} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$-\frac{2}{7}+\frac{1\times 6}{3\times 11}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 6}{3\times 11}.

$$-\frac{2}{7}+\frac{6}{33}$$

Whakahekea te hautanga \frac{6}{33} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{2}{7}+\frac{2}{11}$$

Ko te maha noa iti rawa atu o 7 me 11 ko 77. Me tahuri -\frac{2}{7} me \frac{2}{11} ki te hautau me te tautūnga 77.

$$-\frac{22}{77}+\frac{14}{77}$$

Tā te mea he rite te tauraro o -\frac{22}{77} me \frac{14}{77}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-22+14}{77}$$

Tāpirihia te -22 ki te 14, ka -8.

$$-\frac{8}{77}$$

Tauwehe

$$-\frac{8}{77} = -0.1038961038961039$$
