Whakaoti i te (1/6-1/4)*(-2)=

$$( \frac { 1 } { 6 } - \frac { 1 } { 4 } ) \times ( - 2 ) =$$

Aromātai

$$\frac{1}{6}\approx 0.166666667$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 6 me 4 ko 12. Me tahuri \frac{1}{6} me \frac{1}{4} ki te hautau me te tautūnga 12.

$$\left(\frac{2}{12}-\frac{3}{12}\right)\left(-2\right)$$

Tā te mea he rite te tauraro o \frac{2}{12} me \frac{3}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2-3}{12}\left(-2\right)$$

Tangohia te 3 i te 2, ka -1.

$$-\frac{1}{12}\left(-2\right)$$

Tuhia te -\frac{1}{12}\left(-2\right) hei hautanga kotahi.

$$\frac{-\left(-2\right)}{12}$$

Whakareatia te -1 ki te -2, ka 2.

$$\frac{2}{12}$$

Whakahekea te hautanga \frac{2}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{6}$$

Tauwehe

$$\frac{1}{2 \cdot 3} = 0.16666666666666666$$
