Ko te maha noa iti rawa atu o 21 me 13 ko 273. Me tahuri \frac{1}{21} me \frac{3}{13} ki te hautau me te tautūnga 273.

$$\frac{13}{273}+\frac{63}{273}-\frac{1}{49}+\frac{2}{65}$$

Tā te mea he rite te tauraro o \frac{13}{273} me \frac{63}{273}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{13+63}{273}-\frac{1}{49}+\frac{2}{65}$$

Tāpirihia te 13 ki te 63, ka 76.

$$\frac{76}{273}-\frac{1}{49}+\frac{2}{65}$$

Ko te maha noa iti rawa atu o 273 me 49 ko 1911. Me tahuri \frac{76}{273} me \frac{1}{49} ki te hautau me te tautūnga 1911.

$$\frac{532}{1911}-\frac{39}{1911}+\frac{2}{65}$$

Tā te mea he rite te tauraro o \frac{532}{1911} me \frac{39}{1911}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{532-39}{1911}+\frac{2}{65}$$

Tangohia te 39 i te 532, ka 493.

$$\frac{493}{1911}+\frac{2}{65}$$

Ko te maha noa iti rawa atu o 1911 me 65 ko 9555. Me tahuri \frac{493}{1911} me \frac{2}{65} ki te hautau me te tautūnga 9555.

$$\frac{2465}{9555}+\frac{294}{9555}$$

Tā te mea he rite te tauraro o \frac{2465}{9555} me \frac{294}{9555}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2465+294}{9555}$$

Tāpirihia te 2465 ki te 294, ka 2759.

$$\frac{2759}{9555}$$
