Ngā Upane Otinga

Whakahekea te hautanga \frac{64}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{-6+\frac{32}{5}}{-8}\left(-3\right)$$

Me tahuri te -6 ki te hautau -\frac{30}{5}.

$$\frac{-\frac{30}{5}+\frac{32}{5}}{-8}\left(-3\right)$$

Tā te mea he rite te tauraro o -\frac{30}{5} me \frac{32}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{-30+32}{5}}{-8}\left(-3\right)$$

Tāpirihia te -30 ki te 32, ka 2.

$$\frac{\frac{2}{5}}{-8}\left(-3\right)$$

Tuhia te \frac{\frac{2}{5}}{-8} hei hautanga kotahi.

$$\frac{2}{5\left(-8\right)}\left(-3\right)$$

Whakareatia te 5 ki te -8, ka -40.

$$\frac{2}{-40}\left(-3\right)$$

Whakahekea te hautanga \frac{2}{-40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{1}{20}\left(-3\right)$$

Tuhia te -\frac{1}{20}\left(-3\right) hei hautanga kotahi.

$$\frac{-\left(-3\right)}{20}$$

Whakareatia te -1 ki te -3, ka 3.

$$\frac{3}{20}$$

Tauwehe

$$\frac{3}{2 ^ {2} \cdot 5} = 0.15$$
