Whakaoti i te 6-(-2)/-2+(-7)/(3(-4))(25/5)

$$\frac { 6 - ( - 2 ) } { - 2 } + \frac { ( - 7 ) } { ( 3 ( - 4 ) ) } ( \frac { 25 } { 5 } )$$

Aromātai

$$-\frac{13}{12}\approx -1.083333333$$

Ngā Upane Otinga

Ko te tauaro o -2 ko 2.

$$\frac{6+2}{-2}+\frac{-7}{3\left(-4\right)}\times \frac{25}{5}$$

Tāpirihia te 6 ki te 2, ka 8.

$$\frac{8}{-2}+\frac{-7}{3\left(-4\right)}\times \frac{25}{5}$$

Whakawehea te 8 ki te -2, kia riro ko -4.

$$-4+\frac{-7}{3\left(-4\right)}\times \frac{25}{5}$$

Whakareatia te 3 ki te -4, ka -12.

$$-4+\frac{-7}{-12}\times \frac{25}{5}$$

Ka taea te hautanga \frac{-7}{-12} te whakamāmā ki te \frac{7}{12} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$-4+\frac{7}{12}\times \frac{25}{5}$$

Whakawehea te 25 ki te 5, kia riro ko 5.

$$-4+\frac{7}{12}\times 5$$

Tuhia te \frac{7}{12}\times 5 hei hautanga kotahi.

$$-4+\frac{7\times 5}{12}$$

Whakareatia te 7 ki te 5, ka 35.

$$-4+\frac{35}{12}$$

Me tahuri te -4 ki te hautau -\frac{48}{12}.

$$-\frac{48}{12}+\frac{35}{12}$$

Tā te mea he rite te tauraro o -\frac{48}{12} me \frac{35}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-48+35}{12}$$

Tāpirihia te -48 ki te 35, ka -13.

$$-\frac{13}{12}$$

Tauwehe

$$-\frac{13}{12} = -1\frac{1}{12} = -1.0833333333333333$$
