Ngā Upane Otinga

Ko te maha noa iti rawa atu o 9 me 12 ko 36. Me tahuri \frac{7}{9} me \frac{11}{12} ki te hautau me te tautūnga 36.

$$\frac{45-\left(\frac{28}{36}-\frac{33}{36}+\frac{5}{6}\right)\times 36}{5}$$

Tā te mea he rite te tauraro o \frac{28}{36} me \frac{33}{36}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{45-\left(\frac{28-33}{36}+\frac{5}{6}\right)\times 36}{5}$$

Tangohia te 33 i te 28, ka -5.

$$\frac{45-\left(-\frac{5}{36}+\frac{5}{6}\right)\times 36}{5}$$

Ko te maha noa iti rawa atu o 36 me 6 ko 36. Me tahuri -\frac{5}{36} me \frac{5}{6} ki te hautau me te tautūnga 36.

$$\frac{45-\left(-\frac{5}{36}+\frac{30}{36}\right)\times 36}{5}$$

Tā te mea he rite te tauraro o -\frac{5}{36} me \frac{30}{36}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{45-\frac{-5+30}{36}\times 36}{5}$$

Tāpirihia te -5 ki te 30, ka 25.

$$\frac{45-\frac{25}{36}\times 36}{5}$$

Me whakakore te 36 me te 36.

$$\frac{45-25}{5}$$

Tangohia te 25 i te 45, ka 20.

$$\frac{20}{5}$$

Whakawehea te 20 ki te 5, kia riro ko 4.

$$4$$
