Ngā Upane Otinga

Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri \frac{3}{8} me \frac{7}{4} ki te hautau me te tautūnga 8.

$$\frac{3}{8}-\frac{14}{8}+\frac{2}{161}$$

Tā te mea he rite te tauraro o \frac{3}{8} me \frac{14}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3-14}{8}+\frac{2}{161}$$

Tangohia te 14 i te 3, ka -11.

$$-\frac{11}{8}+\frac{2}{161}$$

Ko te maha noa iti rawa atu o 8 me 161 ko 1288. Me tahuri -\frac{11}{8} me \frac{2}{161} ki te hautau me te tautūnga 1288.

$$-\frac{1771}{1288}+\frac{16}{1288}$$

Tā te mea he rite te tauraro o -\frac{1771}{1288} me \frac{16}{1288}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1771+16}{1288}$$

Tāpirihia te -1771 ki te 16, ka -1755.

$$-\frac{1755}{1288}$$

Tauwehe

$$-\frac{1755}{1288} = -1\frac{467}{1288} = -1.3625776397515528$$
