Aromātai

$$\frac{93}{8}=11.625$$

Ngā Upane Otinga

Whakareatia te 7 ki te 8, ka 56.

$$\frac{56+1}{8}+\frac{4\times 2+1}{2}-0\times 75$$

Tāpirihia te 56 ki te 1, ka 57.

$$\frac{57}{8}+\frac{4\times 2+1}{2}-0\times 75$$

Whakareatia te 4 ki te 2, ka 8.

$$\frac{57}{8}+\frac{8+1}{2}-0\times 75$$

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{57}{8}+\frac{9}{2}-0\times 75$$

Ko te maha noa iti rawa atu o 8 me 2 ko 8. Me tahuri \frac{57}{8} me \frac{9}{2} ki te hautau me te tautūnga 8.

$$\frac{57}{8}+\frac{36}{8}-0\times 75$$

Tā te mea he rite te tauraro o \frac{57}{8} me \frac{36}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{57+36}{8}-0\times 75$$

Tāpirihia te 57 ki te 36, ka 93.

$$\frac{93}{8}-0\times 75$$

Whakareatia te 0 ki te 75, ka 0.

$$\frac{93}{8}-0$$

Tangohia te 0 i te \frac{93}{8}, ka \frac{93}{8}.

$$\frac{93}{8}$$

Tauwehe

$$\frac{3 \cdot 31}{2 ^ {3}} = 11\frac{5}{8} = 11.625$$
