Ngā Upane Otinga

Ko te maha noa iti rawa atu o 5 me 8 ko 40. Me tahuri \frac{39}{5} me \frac{35}{8} ki te hautau me te tautūnga 40.

$$\frac{312}{40}-\frac{175}{40}+\frac{51}{20}$$

Tā te mea he rite te tauraro o \frac{312}{40} me \frac{175}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{312-175}{40}+\frac{51}{20}$$

Tangohia te 175 i te 312, ka 137.

$$\frac{137}{40}+\frac{51}{20}$$

Ko te maha noa iti rawa atu o 40 me 20 ko 40. Me tahuri \frac{137}{40} me \frac{51}{20} ki te hautau me te tautūnga 40.

$$\frac{137}{40}+\frac{102}{40}$$

Tā te mea he rite te tauraro o \frac{137}{40} me \frac{102}{40}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{137+102}{40}$$

Tāpirihia te 137 ki te 102, ka 239.

$$\frac{239}{40}$$

Tauwehe

$$\frac{239}{2 ^ {3} \cdot 5} = 5\frac{39}{40} = 5.975$$
