Ngā Upane Otinga

Tuhia te \frac{3}{2}\times 4 hei hautanga kotahi.

$$\left(-\frac{3\times 4}{2}\right)\times \frac{\frac{1}{6}}{\frac{1}{2}}\times \frac{3}{10}$$

Whakareatia te 3 ki te 4, ka 12.

$$\left(-\frac{12}{2}\right)\times \frac{\frac{1}{6}}{\frac{1}{2}}\times \frac{3}{10}$$

Whakawehea te 12 ki te 2, kia riro ko 6.

$$-6\times \frac{\frac{1}{6}}{\frac{1}{2}}\times \frac{3}{10}$$

Whakawehe \frac{1}{6} ki te \frac{1}{2} mā te whakarea \frac{1}{6} ki te tau huripoki o \frac{1}{2}.

$$-6\times \frac{1}{6}\times 2\times \frac{3}{10}$$

Whakareatia te \frac{1}{6} ki te 2, ka \frac{2}{6}.

$$-6\times \frac{2}{6}\times \frac{3}{10}$$

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

$$-6\times \frac{1}{3}\times \frac{3}{10}$$

Whakareatia te -6 ki te \frac{1}{3}, ka \frac{-6}{3}.

$$\frac{-6}{3}\times \frac{3}{10}$$

Whakawehea te -6 ki te 3, kia riro ko -2.

$$-2\times \frac{3}{10}$$

Tuhia te -2\times \frac{3}{10} hei hautanga kotahi.

$$\frac{-2\times 3}{10}$$

Whakareatia te -2 ki te 3, ka -6.

$$\frac{-6}{10}$$

Whakahekea te hautanga \frac{-6}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{3}{5}$$

Tauwehe

$$-\frac{3}{5} = -0.6$$
