Whakaoti i te 9/9-15/2+-7/6

$$\frac { 9 } { 9 } - \frac { 15 } { 2 } + \frac { - 7 } { 6 }$$

Aromātai

$$-\frac{23}{3}\approx -7.666666667$$

Ngā Upane Otinga

Whakawehea te 9 ki te 9, kia riro ko 1.

$$1-\frac{15}{2}+\frac{-7}{6}$$

Me tahuri te 1 ki te hautau \frac{2}{2}.

$$\frac{2}{2}-\frac{15}{2}+\frac{-7}{6}$$

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

$$\frac{2-15}{2}+\frac{-7}{6}$$

Tangohia te 15 i te 2, ka -13.

$$-\frac{13}{2}+\frac{-7}{6}$$

Ka taea te hautanga \frac{-7}{6} te tuhi anō ko -\frac{7}{6} mā te tango i te tohu tōraro.

$$-\frac{13}{2}-\frac{7}{6}$$

Ko te maha noa iti rawa atu o 2 me 6 ko 6. Me tahuri -\frac{13}{2} me \frac{7}{6} ki te hautau me te tautūnga 6.

$$-\frac{39}{6}-\frac{7}{6}$$

Tā te mea he rite te tauraro o -\frac{39}{6} me \frac{7}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-39-7}{6}$$

Tangohia te 7 i te -39, ka -46.

$$\frac{-46}{6}$$

Whakahekea te hautanga \frac{-46}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{23}{3}$$

Tauwehe

$$-\frac{23}{3} = -7\frac{2}{3} = -7.666666666666667$$
