$$-\frac{17}{6}\approx -2.833333333$$

Ngā Upane Otinga

Whakareatia te 2 ki te 12, ka 24.

$$-\frac{3}{4}-\frac{24+1}{12}$$

Tāpirihia te 24 ki te 1, ka 25.

$$-\frac{3}{4}-\frac{25}{12}$$

Ko te maha noa iti rawa atu o 4 me 12 ko 12. Me tahuri -\frac{3}{4} me \frac{25}{12} ki te hautau me te tautūnga 12.

$$-\frac{9}{12}-\frac{25}{12}$$

Tā te mea he rite te tauraro o -\frac{9}{12} me \frac{25}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-9-25}{12}$$

Tangohia te 25 i te -9, ka -34.

$$\frac{-34}{12}$$

Whakahekea te hautanga \frac{-34}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{17}{6}$$

Tauwehe

$$-\frac{17}{6} = -2\frac{5}{6} = -2.8333333333333335$$
