Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{8}{8}.

$$160\left(\frac{8}{8}-\frac{1}{8}-\frac{1}{4}\right)$$

Tā te mea he rite te tauraro o \frac{8}{8} me \frac{1}{8}, me tango rāua mā te tango i ō raua taurunga.

$$160\left(\frac{8-1}{8}-\frac{1}{4}\right)$$

Tangohia te 1 i te 8, ka 7.

$$160\left(\frac{7}{8}-\frac{1}{4}\right)$$

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

$$160\left(\frac{7}{8}-\frac{2}{8}\right)$$

Tā te mea he rite te tauraro o \frac{7}{8} me \frac{2}{8}, me tango rāua mā te tango i ō raua taurunga.

$$160\times \frac{7-2}{8}$$

Tangohia te 2 i te 7, ka 5.

$$160\times \frac{5}{8}$$

Tuhia te 160\times \frac{5}{8} hei hautanga kotahi.

$$\frac{160\times 5}{8}$$

Whakareatia te 160 ki te 5, ka 800.

$$\frac{800}{8}$$

Whakawehea te 800 ki te 8, kia riro ko 100.
