Ngā Upane Otinga

Tuhia te -\frac{5}{7}\left(-14\right) hei hautanga kotahi.

$$\frac{-5\left(-14\right)}{7}\times \frac{3\times 2+1}{2}\times \frac{2}{7}$$

Whakareatia te -5 ki te -14, ka 70.

$$\frac{70}{7}\times \frac{3\times 2+1}{2}\times \frac{2}{7}$$

Whakawehea te 70 ki te 7, kia riro ko 10.

$$10\times \frac{3\times 2+1}{2}\times \frac{2}{7}$$

Whakareatia te 3 ki te 2, ka 6.

$$10\times \frac{6+1}{2}\times \frac{2}{7}$$

Tāpirihia te 6 ki te 1, ka 7.

$$10\times \frac{7}{2}\times \frac{2}{7}$$

Tuhia te 10\times \frac{7}{2} hei hautanga kotahi.

$$\frac{10\times 7}{2}\times \frac{2}{7}$$

Whakareatia te 10 ki te 7, ka 70.

$$\frac{70}{2}\times \frac{2}{7}$$

Whakawehea te 70 ki te 2, kia riro ko 35.

$$35\times \frac{2}{7}$$

Tuhia te 35\times \frac{2}{7} hei hautanga kotahi.

$$\frac{35\times 2}{7}$$

Whakareatia te 35 ki te 2, ka 70.

$$\frac{70}{7}$$

Whakawehea te 70 ki te 7, kia riro ko 10.

$$10$$
