Aromātai

$$\frac{667}{40}=16.675$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 5 me 8 ko 40. Me tahuri \frac{4}{5} me \frac{1}{8} ki te hautau me te tautūnga 40.

$$\frac{32}{40}-\frac{5}{40}+16-0\times 13$$

Tā te mea he rite te tauraro o \frac{32}{40} me \frac{5}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{32-5}{40}+16-0\times 13$$

Tangohia te 5 i te 32, ka 27.

$$\frac{27}{40}+16-0\times 13$$

Whakareatia te 0 ki te 13, ka 0.

$$\frac{27}{40}+16-0$$

Tangohia te 0 i te 16, ka 16.

$$\frac{27}{40}+16$$

Me tahuri te 16 ki te hautau \frac{640}{40}.

$$\frac{27}{40}+\frac{640}{40}$$

Tā te mea he rite te tauraro o \frac{27}{40} me \frac{640}{40}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{27+640}{40}$$

Tāpirihia te 27 ki te 640, ka 667.

$$\frac{667}{40}$$

Tauwehe

$$\frac{23 \cdot 29}{2 ^ {3} \cdot 5} = 16\frac{27}{40} = 16.675$$
