Ngā Upane Otinga

Whakawehe 2 ki te \frac{27}{25} mā te whakarea 2 ki te tau huripoki o \frac{27}{25}.

$$sort(0,2\times \frac{25}{27}-\frac{2}{3})$$

Tuhia te 2\times \frac{25}{27} hei hautanga kotahi.

$$sort(0,\frac{2\times 25}{27}-\frac{2}{3})$$

Whakareatia te 2 ki te 25, ka 50.

$$sort(0,\frac{50}{27}-\frac{2}{3})$$

Ko te maha noa iti rawa atu o 27 me 3 ko 27. Me tahuri \frac{50}{27} me \frac{2}{3} ki te hautau me te tautūnga 27.

$$sort(0,\frac{50}{27}-\frac{18}{27})$$

Tā te mea he rite te tauraro o \frac{50}{27} me \frac{18}{27}, me tango rāua mā te tango i ō raua taurunga.

$$sort(0,\frac{50-18}{27})$$

Tangohia te 18 i te 50, ka 32.

$$sort(0,\frac{32}{27})$$

Tahuritia ngā tau ā-ira i te rārangi 0,\frac{32}{27} ki ngā hautanga.

$$0,\frac{32}{27}$$
