Ngā Upane Otinga

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

$$\frac{2}{4}+\frac{1}{4}-\frac{1}{3}$$

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

$$\frac{2+1}{4}-\frac{1}{3}$$

Tāpirihia te 2 ki te 1, ka 3.

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

Ko te maha noa iti rawa atu o 4 me 3 ko 12. Me tahuri \frac{3}{4} me \frac{1}{3} ki te hautau me te tautūnga 12.

$$\frac{9}{12}-\frac{4}{12}$$

Tā te mea he rite te tauraro o \frac{9}{12} me \frac{4}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{9-4}{12}$$

Tangohia te 4 i te 9, ka 5.

$$\frac{5}{12}$$

Tauwehe

$$\frac{5}{2 ^ {2} \cdot 3} = 0.4166666666666667$$
