Ngā Upane Otinga

Tā te mea he rite te tauraro o \frac{5}{7} me \frac{3}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{5+3}{7}+\frac{3}{12}$$

Tāpirihia te 5 ki te 3, ka 8.

$$\frac{8}{7}+\frac{3}{12}$$

Whakahekea te hautanga \frac{3}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{8}{7}+\frac{1}{4}$$

Ko te maha noa iti rawa atu o 7 me 4 ko 28. Me tahuri \frac{8}{7} me \frac{1}{4} ki te hautau me te tautūnga 28.

$$\frac{32}{28}+\frac{7}{28}$$

Tā te mea he rite te tauraro o \frac{32}{28} me \frac{7}{28}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{32+7}{28}$$

Tāpirihia te 32 ki te 7, ka 39.

$$\frac{39}{28}$$

Tauwehe

$$\frac{3 \cdot 13}{2 ^ {2} \cdot 7} = 1\frac{11}{28} = 1.3928571428571428$$
