Ngā Upane Otinga

Whakahekea te hautanga \frac{2}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{4}+\frac{3}{6}-1$$

Whakahekea te hautanga \frac{3}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{1}{4}+\frac{1}{2}-1$$

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

$$\frac{1}{4}+\frac{2}{4}-1$$

Tā te mea he rite te tauraro o \frac{1}{4} me \frac{2}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1+2}{4}-1$$

Tāpirihia te 1 ki te 2, ka 3.

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

Me tahuri te 1 ki te hautau \frac{4}{4}.

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

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

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

Tangohia te 4 i te 3, ka -1.

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

Tauwehe

$$-\frac{1}{4} = -0.25$$
