Ngā Upane Otinga

Ko te maha noa iti rawa atu o 30 me 60 ko 60. Me tahuri \frac{7}{30} me \frac{7}{60} ki te hautau me te tautūnga 60.

$$\frac{14}{60}+\frac{7}{60}+\frac{7}{23}$$

Tā te mea he rite te tauraro o \frac{14}{60} me \frac{7}{60}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{14+7}{60}+\frac{7}{23}$$

Tāpirihia te 14 ki te 7, ka 21.

$$\frac{21}{60}+\frac{7}{23}$$

Whakahekea te hautanga \frac{21}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{7}{20}+\frac{7}{23}$$

Ko te maha noa iti rawa atu o 20 me 23 ko 460. Me tahuri \frac{7}{20} me \frac{7}{23} ki te hautau me te tautūnga 460.

$$\frac{161}{460}+\frac{140}{460}$$

Tā te mea he rite te tauraro o \frac{161}{460} me \frac{140}{460}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{161+140}{460}$$

Tāpirihia te 161 ki te 140, ka 301.
