Ngā Upane Otinga

Whakareatia te 4 ki te 9, ka 36.

$$\frac{36+2}{9}+\frac{2\times 18+5}{18}\times 11$$

Tāpirihia te 36 ki te 2, ka 38.

$$\frac{38}{9}+\frac{2\times 18+5}{18}\times 11$$

Whakareatia te 2 ki te 18, ka 36.

$$\frac{38}{9}+\frac{36+5}{18}\times 11$$

Tāpirihia te 36 ki te 5, ka 41.

$$\frac{38}{9}+\frac{41}{18}\times 11$$

Tuhia te \frac{41}{18}\times 11 hei hautanga kotahi.

$$\frac{38}{9}+\frac{41\times 11}{18}$$

Whakareatia te 41 ki te 11, ka 451.

$$\frac{38}{9}+\frac{451}{18}$$

Ko te maha noa iti rawa atu o 9 me 18 ko 18. Me tahuri \frac{38}{9} me \frac{451}{18} ki te hautau me te tautūnga 18.

$$\frac{76}{18}+\frac{451}{18}$$

Tā te mea he rite te tauraro o \frac{76}{18} me \frac{451}{18}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{76+451}{18}$$

Tāpirihia te 76 ki te 451, ka 527.

$$\frac{527}{18}$$

Tauwehe

$$\frac{17 \cdot 31}{2 \cdot 3 ^ {2}} = 29\frac{5}{18} = 29.27777777777778$$
