Ngā Upane Otinga

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{1}{2} me \frac{3}{4} ki te hautau me te tautūnga 4.

$$\frac{\frac{2}{4}-\frac{3}{4}-\frac{1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

Tā te mea he rite te tauraro o \frac{2}{4} me \frac{3}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{2-3}{4}-\frac{1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

Tangohia te 3 i te 2, ka -1.

$$\frac{-\frac{1}{4}-\frac{1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

Ko te maha noa iti rawa atu o 4 me 12 ko 12. Me tahuri -\frac{1}{4} me \frac{1}{12} ki te hautau me te tautūnga 12.

$$\frac{-\frac{3}{12}-\frac{1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

Tā te mea he rite te tauraro o -\frac{3}{12} me \frac{1}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{-3-1}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

Tangohia te 1 i te -3, ka -4.

$$\frac{\frac{-4}{12}}{\left(-\frac{1}{2}\right)^{2}}$$

Whakahekea te hautanga \frac{-4}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{-\frac{1}{3}}{\left(-\frac{1}{2}\right)^{2}}$$

Tātaihia te -\frac{1}{2} mā te pū o 2, kia riro ko \frac{1}{4}.

$$\frac{-\frac{1}{3}}{\frac{1}{4}}$$

Whakawehe -\frac{1}{3} ki te \frac{1}{4} mā te whakarea -\frac{1}{3} ki te tau huripoki o \frac{1}{4}.

$$-\frac{1}{3}\times 4$$

Tuhia te -\frac{1}{3}\times 4 hei hautanga kotahi.

$$\frac{-4}{3}$$

Ka taea te hautanga \frac{-4}{3} te tuhi anō ko -\frac{4}{3} mā te tango i te tohu tōraro.

$$-\frac{4}{3}$$

Tauwehe

$$-\frac{4}{3} = -1\frac{1}{3} = -1.3333333333333333$$
