Aromātai

$$10.875$$

Ngā Upane Otinga

Whakareatia te 7 ki te 8, ka 56.

$$\frac{56+1}{8}+\frac{4\times 2+1}{2}-0.75$$

Tāpirihia te 56 ki te 1, ka 57.

$$\frac{57}{8}+\frac{4\times 2+1}{2}-0.75$$

Whakareatia te 4 ki te 2, ka 8.

$$\frac{57}{8}+\frac{8+1}{2}-0.75$$

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{57}{8}+\frac{9}{2}-0.75$$

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.

$$\frac{57}{8}+\frac{36}{8}-0.75$$

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.

$$\frac{57+36}{8}-0.75$$

Tāpirihia te 57 ki te 36, ka 93.

$$\frac{93}{8}-0.75$$

Me tahuri ki tau ā-ira 0.75 ki te hautau \frac{75}{100}. Whakahekea te hautanga \frac{75}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{93}{8}-\frac{3}{4}$$

Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri \frac{93}{8} me \frac{3}{4} ki te hautau me te tautūnga 8.

$$\frac{93}{8}-\frac{6}{8}$$

Tā te mea he rite te tauraro o \frac{93}{8} me \frac{6}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{93-6}{8}$$

Tangohia te 6 i te 93, ka 87.

$$\frac{87}{8}$$

Tauwehe

$$\frac{3 \cdot 29}{2 ^ {3}} = 10\frac{7}{8} = 10.875$$
