Ngā Upane Otinga

Whakareatia te 1 ki te 2, ka 2.

$$\frac{3}{8}+\frac{2+1}{2}+\frac{1\times 4+1}{4}$$

Tāpirihia te 2 ki te 1, ka 3.

$$\frac{3}{8}+\frac{3}{2}+\frac{1\times 4+1}{4}$$

Ko te maha noa iti rawa atu o 8 me 2 ko 8. Me tahuri \frac{3}{8} me \frac{3}{2} ki te hautau me te tautūnga 8.

$$\frac{3}{8}+\frac{12}{8}+\frac{1\times 4+1}{4}$$

Tā te mea he rite te tauraro o \frac{3}{8} me \frac{12}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+12}{8}+\frac{1\times 4+1}{4}$$

Tāpirihia te 3 ki te 12, ka 15.

$$\frac{15}{8}+\frac{1\times 4+1}{4}$$

Whakareatia te 1 ki te 4, ka 4.

$$\frac{15}{8}+\frac{4+1}{4}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{15}{8}+\frac{5}{4}$$

Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri \frac{15}{8} me \frac{5}{4} ki te hautau me te tautūnga 8.

$$\frac{15}{8}+\frac{10}{8}$$

Tā te mea he rite te tauraro o \frac{15}{8} me \frac{10}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{15+10}{8}$$

Tāpirihia te 15 ki te 10, ka 25.

$$\frac{25}{8}$$

Tauwehe

$$\frac{5 ^ {2}}{2 ^ {3}} = 3\frac{1}{8} = 3.125$$
