Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 4 ko 12. Me tahuri \frac{2}{3} me \frac{3}{4} ki te hautau me te tautūnga 12.

$$\frac{8}{12}-\frac{9}{12}+\frac{5}{2}-\frac{1}{2}$$

Tā te mea he rite te tauraro o \frac{8}{12} me \frac{9}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{8-9}{12}+\frac{5}{2}-\frac{1}{2}$$

Tangohia te 9 i te 8, ka -1.

$$-\frac{1}{12}+\frac{5}{2}-\frac{1}{2}$$

Ko te maha noa iti rawa atu o 12 me 2 ko 12. Me tahuri -\frac{1}{12} me \frac{5}{2} ki te hautau me te tautūnga 12.

$$-\frac{1}{12}+\frac{30}{12}-\frac{1}{2}$$

Tā te mea he rite te tauraro o -\frac{1}{12} me \frac{30}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1+30}{12}-\frac{1}{2}$$

Tāpirihia te -1 ki te 30, ka 29.

$$\frac{29}{12}-\frac{1}{2}$$

Ko te maha noa iti rawa atu o 12 me 2 ko 12. Me tahuri \frac{29}{12} me \frac{1}{2} ki te hautau me te tautūnga 12.

$$\frac{29}{12}-\frac{6}{12}$$

Tā te mea he rite te tauraro o \frac{29}{12} me \frac{6}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{29-6}{12}$$

Tangohia te 6 i te 29, ka 23.

$$\frac{23}{12}$$

Tauwehe

$$\frac{23}{2 ^ {2} \cdot 3} = 1\frac{11}{12} = 1.9166666666666667$$
