Aromātai

$$-\frac{16}{3}\approx -5.333333333$$

Ngā Upane Otinga

Whakawehe \frac{4\times 3+2}{3} ki te \frac{-7}{8} mā te whakarea \frac{4\times 3+2}{3} ki te tau huripoki o \frac{-7}{8}.

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

Whakareatia te 4 ki te 3, ka 12.

$$\frac{\left(12+2\right)\times 8}{3\left(-7\right)}$$

Tāpirihia te 12 ki te 2, ka 14.

$$\frac{14\times 8}{3\left(-7\right)}$$

Whakareatia te 14 ki te 8, ka 112.

$$\frac{112}{3\left(-7\right)}$$

Whakareatia te 3 ki te -7, ka -21.

$$\frac{112}{-21}$$

Whakahekea te hautanga \frac{112}{-21} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.
