Ngā Upane Otinga

Whakarohaina te \frac{2.1}{7} mā te whakarea i te taurunga me te tauraro ki te 10.

$$sort(10,1-\frac{\frac{21}{70}-0.05}{2})$$

Whakahekea te hautanga \frac{21}{70} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$sort(10,1-\frac{\frac{3}{10}-0.05}{2})$$

Me tahuri ki tau ā-ira 0.05 ki te hautau \frac{5}{100}. Whakahekea te hautanga \frac{5}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$sort(10,1-\frac{\frac{3}{10}-\frac{1}{20}}{2})$$

Ko te maha noa iti rawa atu o 10 me 20 ko 20. Me tahuri \frac{3}{10} me \frac{1}{20} ki te hautau me te tautūnga 20.

$$sort(10,1-\frac{\frac{6}{20}-\frac{1}{20}}{2})$$

Tā te mea he rite te tauraro o \frac{6}{20} me \frac{1}{20}, me tango rāua mā te tango i ō raua taurunga.

$$sort(10,1-\frac{\frac{6-1}{20}}{2})$$

Tangohia te 1 i te 6, ka 5.

$$sort(10,1-\frac{\frac{5}{20}}{2})$$

Whakahekea te hautanga \frac{5}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$sort(10,1-\frac{\frac{1}{4}}{2})$$

Tuhia te \frac{\frac{1}{4}}{2} hei hautanga kotahi.

$$sort(10,1-\frac{1}{4\times 2})$$

Whakareatia te 4 ki te 2, ka 8.

$$sort(10,1-\frac{1}{8})$$

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

$$sort(10,\frac{8}{8}-\frac{1}{8})$$

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.

$$sort(10,\frac{8-1}{8})$$

Tangohia te 1 i te 8, ka 7.

$$sort(10,\frac{7}{8})$$

Tahuritia ngā tau ā-ira i te rārangi 10,\frac{7}{8} ki ngā hautanga.

$$10,\frac{7}{8}$$

Hei kōmaka i te rārangi, me tīmata mai i tētahi huānga 10 kotahi.

$$10$$

Me kōkuhu te \frac{7}{8} ki te tauwāhi tika i te rārangi hōu.

$$\frac{7}{8},10$$
