Ngā Upane Otinga

Ko te maha noa iti rawa atu o 5 me 8 ko 40. Me tahuri \frac{34}{5} me \frac{35}{8} ki te hautau me te tautūnga 40.

$$\frac{272}{40}-\frac{175}{40}+\frac{51}{20}$$

Tā te mea he rite te tauraro o \frac{272}{40} me \frac{175}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{272-175}{40}+\frac{51}{20}$$

Tangohia te 175 i te 272, ka 97.

$$\frac{97}{40}+\frac{51}{20}$$

Ko te maha noa iti rawa atu o 40 me 20 ko 40. Me tahuri \frac{97}{40} me \frac{51}{20} ki te hautau me te tautūnga 40.

$$\frac{97}{40}+\frac{102}{40}$$

Tā te mea he rite te tauraro o \frac{97}{40} me \frac{102}{40}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{97+102}{40}$$

Tāpirihia te 97 ki te 102, ka 199.

$$\frac{199}{40}$$

Tauwehe

$$\frac{199}{2 ^ {3} \cdot 5} = 4\frac{39}{40} = 4.975$$
