Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{1}{2} me \frac{3}{4} ki te hautau me te tautūnga 4.

$$\left(\frac{2}{4}+\frac{3}{4}-2\right)\left(-8\right)$$

Tā te mea he rite te tauraro o \frac{2}{4} me \frac{3}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\left(\frac{2+3}{4}-2\right)\left(-8\right)$$

Tāpirihia te 2 ki te 3, ka 5.

$$\left(\frac{5}{4}-2\right)\left(-8\right)$$

Me tahuri te 2 ki te hautau \frac{8}{4}.

$$\left(\frac{5}{4}-\frac{8}{4}\right)\left(-8\right)$$

Tā te mea he rite te tauraro o \frac{5}{4} me \frac{8}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{5-8}{4}\left(-8\right)$$

Tangohia te 8 i te 5, ka -3.

$$-\frac{3}{4}\left(-8\right)$$

Tuhia te -\frac{3}{4}\left(-8\right) hei hautanga kotahi.

$$\frac{-3\left(-8\right)}{4}$$

Whakareatia te -3 ki te -8, ka 24.

$$\frac{24}{4}$$

Whakawehea te 24 ki te 4, kia riro ko 6.

$$6$$
