Whakaoti i te -1/2+5/6-2/9=

$$- \frac { 1 } { 2 } + \frac { 5 } { 6 } - \frac { 2 } { 9 } =$$

Aromātai

$$\frac{1}{9}\approx 0.111111111$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 2 me 6 ko 6. Me tahuri -\frac{1}{2} me \frac{5}{6} ki te hautau me te tautūnga 6.

$$-\frac{3}{6}+\frac{5}{6}-\frac{2}{9}$$

Tā te mea he rite te tauraro o -\frac{3}{6} me \frac{5}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-3+5}{6}-\frac{2}{9}$$

Tāpirihia te -3 ki te 5, ka 2.

$$\frac{2}{6}-\frac{2}{9}$$

Whakahekea te hautanga \frac{2}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

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

Ko te maha noa iti rawa atu o 3 me 9 ko 9. Me tahuri \frac{1}{3} me \frac{2}{9} ki te hautau me te tautūnga 9.

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

Tā te mea he rite te tauraro o \frac{3}{9} me \frac{2}{9}, me tango rāua mā te tango i ō raua taurunga.

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

Tangohia te 2 i te 3, ka 1.

$$\frac{1}{9}$$

Tauwehe

$$\frac{1}{3 ^ {2}} = 0.1111111111111111$$
