Ngā Upane Otinga

Ko te maha noa iti rawa atu o 5 me 2 ko 10. Me tahuri \frac{2}{5} me \frac{7}{2} ki te hautau me te tautūnga 10.

$$\frac{4}{10}+\frac{35}{10}+\frac{6}{9}$$

Tā te mea he rite te tauraro o \frac{4}{10} me \frac{35}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{4+35}{10}+\frac{6}{9}$$

Tāpirihia te 4 ki te 35, ka 39.

$$\frac{39}{10}+\frac{6}{9}$$

Whakahekea te hautanga \frac{6}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{39}{10}+\frac{2}{3}$$

Ko te maha noa iti rawa atu o 10 me 3 ko 30. Me tahuri \frac{39}{10} me \frac{2}{3} ki te hautau me te tautūnga 30.

$$\frac{117}{30}+\frac{20}{30}$$

Tā te mea he rite te tauraro o \frac{117}{30} me \frac{20}{30}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{117+20}{30}$$

Tāpirihia te 117 ki te 20, ka 137.

$$\frac{137}{30}$$

Tauwehe

$$\frac{137}{2 \cdot 3 \cdot 5} = 4\frac{17}{30} = 4.566666666666666$$
