Ngā Upane Otinga

Ka taea te hautanga \frac{-2}{7} te tuhi anō ko -\frac{2}{7} mā te tango i te tohu tōraro.

$$\frac{-\frac{2}{7}-1}{3}+1$$

Me tahuri te 1 ki te hautau \frac{7}{7}.

$$\frac{-\frac{2}{7}-\frac{7}{7}}{3}+1$$

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

$$\frac{\frac{-2-7}{7}}{3}+1$$

Tangohia te 7 i te -2, ka -9.

$$\frac{-\frac{9}{7}}{3}+1$$

Tuhia te \frac{-\frac{9}{7}}{3} hei hautanga kotahi.

$$\frac{-9}{7\times 3}+1$$

Whakareatia te 7 ki te 3, ka 21.

$$\frac{-9}{21}+1$$

Whakahekea te hautanga \frac{-9}{21} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{3}{7}+1$$

Me tahuri te 1 ki te hautau \frac{7}{7}.

$$-\frac{3}{7}+\frac{7}{7}$$

Tā te mea he rite te tauraro o -\frac{3}{7} me \frac{7}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-3+7}{7}$$

Tāpirihia te -3 ki te 7, ka 4.

$$\frac{4}{7}$$

Tauwehe

$$\frac{2 ^ {2}}{7} = 0.5714285714285714$$
