Ngā Upane Otinga

Ko te maha noa iti rawa atu o 4 me 6 ko 12. Me tahuri \frac{1}{4} me \frac{1}{6} ki te hautau me te tautūnga 12.

$$\frac{3}{12}+\frac{2}{12}-\frac{2}{9}$$

Tā te mea he rite te tauraro o \frac{3}{12} me \frac{2}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+2}{12}-\frac{2}{9}$$

Tāpirihia te 3 ki te 2, ka 5.

$$\frac{5}{12}-\frac{2}{9}$$

Ko te maha noa iti rawa atu o 12 me 9 ko 36. Me tahuri \frac{5}{12} me \frac{2}{9} ki te hautau me te tautūnga 36.

$$\frac{15}{36}-\frac{8}{36}$$

Tā te mea he rite te tauraro o \frac{15}{36} me \frac{8}{36}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{15-8}{36}$$

Tangohia te 8 i te 15, ka 7.

$$\frac{7}{36}$$

Tauwehe

$$\frac{7}{2 ^ {2} \cdot 3 ^ {2}} = 0.19444444444444445$$
