Whakaoti i te -5/7(-1.4)*31/2*2/7=

$$- \frac { 5 } { 7 } ( - 1.4 ) \cdot 3 \frac { 1 } { 2 } \cdot \frac { 2 } { 7 } =$$

Ngā Upane Otinga

Me tahuri ki tau ā-ira -1.4 ki te hautau -\frac{14}{10}. Whakahekea te hautanga -\frac{14}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{5}{7}\left(-\frac{7}{5}\right)\times \frac{3\times 2+1}{2}\times \frac{2}{7}$$

Me whakarea te -\frac{5}{7} ki te -\frac{7}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-5\left(-7\right)}{7\times 5}\times \frac{3\times 2+1}{2}\times \frac{2}{7}$$

Mahia ngā whakarea i roto i te hautanga \frac{-5\left(-7\right)}{7\times 5}.

$$\frac{35}{35}\times \frac{3\times 2+1}{2}\times \frac{2}{7}$$

Whakawehea te 35 ki te 35, kia riro ko 1.

$$1\times \frac{3\times 2+1}{2}\times \frac{2}{7}$$

Whakareatia te 3 ki te 2, ka 6.

$$1\times \frac{6+1}{2}\times \frac{2}{7}$$

Tāpirihia te 6 ki te 1, ka 7.

$$1\times \frac{7}{2}\times \frac{2}{7}$$

Whakareatia te 1 ki te \frac{7}{2}, ka \frac{7}{2}.

$$\frac{7}{2}\times \frac{2}{7}$$

Me whakakore atu te \frac{7}{2} me tōna tau utu \frac{2}{7}.
