Aromātai

$$-\frac{11}{12}\approx -0.916666667$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 4 ko 12. Me tahuri \frac{1}{3} me \frac{3}{4} ki te hautau me te tautūnga 12.

$$\frac{4}{12}+\frac{9}{12}-2$$

Tā te mea he rite te tauraro o \frac{4}{12} me \frac{9}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{4+9}{12}-2$$

Tāpirihia te 4 ki te 9, ka 13.

$$\frac{13}{12}-2$$

Me tahuri te 2 ki te hautau \frac{24}{12}.

$$\frac{13}{12}-\frac{24}{12}$$

Tā te mea he rite te tauraro o \frac{13}{12} me \frac{24}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{13-24}{12}$$

Tangohia te 24 i te 13, ka -11.

$$-\frac{11}{12}$$

Tauwehe

$$-\frac{11}{12} = -0.9166666666666666$$
