Ngā Upane Otinga

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

$$-\frac{3}{2}-\frac{-5}{8}$$

Ka taea te hautanga \frac{-5}{8} te tuhi anō ko -\frac{5}{8} mā te tango i te tohu tōraro.

$$-\frac{3}{2}-\left(-\frac{5}{8}\right)$$

Ko te tauaro o -\frac{5}{8} ko \frac{5}{8}.

$$-\frac{3}{2}+\frac{5}{8}$$

Ko te maha noa iti rawa atu o 2 me 8 ko 8. Me tahuri -\frac{3}{2} me \frac{5}{8} ki te hautau me te tautūnga 8.

$$-\frac{12}{8}+\frac{5}{8}$$

Tā te mea he rite te tauraro o -\frac{12}{8} me \frac{5}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-12+5}{8}$$

Tāpirihia te -12 ki te 5, ka -7.

$$-\frac{7}{8}$$

Tauwehe

$$-\frac{7}{8} = -0.875$$
