Ngā Upane Otinga

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

$$\frac{1}{3}+\frac{1}{2}-\frac{1}{9}$$

Ko te maha noa iti rawa atu o 3 me 2 ko 6. Me tahuri \frac{1}{3} me \frac{1}{2} ki te hautau me te tautūnga 6.

$$\frac{2}{6}+\frac{3}{6}-\frac{1}{9}$$

Tā te mea he rite te tauraro o \frac{2}{6} me \frac{3}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2+3}{6}-\frac{1}{9}$$

Tāpirihia te 2 ki te 3, ka 5.

$$\frac{5}{6}-\frac{1}{9}$$

Ko te maha noa iti rawa atu o 6 me 9 ko 18. Me tahuri \frac{5}{6} me \frac{1}{9} ki te hautau me te tautūnga 18.

$$\frac{15}{18}-\frac{2}{18}$$

Tā te mea he rite te tauraro o \frac{15}{18} me \frac{2}{18}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{15-2}{18}$$

Tangohia te 2 i te 15, ka 13.

$$\frac{13}{18}$$

Tauwehe

$$\frac{13}{2 \cdot 3 ^ {2}} = 0.7222222222222222$$
