Ko te maha noa iti rawa atu o 12 me 3 ko 12. Me tahuri \frac{5}{12} me \frac{2}{3} ki te hautau me te tautūnga 12.

$$\left(\frac{5}{12}+\frac{8}{12}-\frac{3}{4}\right)\left(-12\right)$$

Tā te mea he rite te tauraro o \frac{5}{12} me \frac{8}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\left(\frac{5+8}{12}-\frac{3}{4}\right)\left(-12\right)$$

Tāpirihia te 5 ki te 8, ka 13.

$$\left(\frac{13}{12}-\frac{3}{4}\right)\left(-12\right)$$

Ko te maha noa iti rawa atu o 12 me 4 ko 12. Me tahuri \frac{13}{12} me \frac{3}{4} ki te hautau me te tautūnga 12.

$$\left(\frac{13}{12}-\frac{9}{12}\right)\left(-12\right)$$

Tā te mea he rite te tauraro o \frac{13}{12} me \frac{9}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{13-9}{12}\left(-12\right)$$

Tangohia te 9 i te 13, ka 4.

$$\frac{4}{12}\left(-12\right)$$

Whakahekea te hautanga \frac{4}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{1}{3}\left(-12\right)$$

Whakareatia te \frac{1}{3} ki te -12, ka \frac{-12}{3}.

$$\frac{-12}{3}$$

Whakawehea te -12 ki te 3, kia riro ko -4.
