Ngā Upane Otinga

Whakareatia te 15 ki te 2, ka 30.

$$\frac{30+1}{2}+\frac{7\times 3+2}{3}-\frac{9\times 9+1}{9}$$

Tāpirihia te 30 ki te 1, ka 31.

$$\frac{31}{2}+\frac{7\times 3+2}{3}-\frac{9\times 9+1}{9}$$

Whakareatia te 7 ki te 3, ka 21.

$$\frac{31}{2}+\frac{21+2}{3}-\frac{9\times 9+1}{9}$$

Tāpirihia te 21 ki te 2, ka 23.

$$\frac{31}{2}+\frac{23}{3}-\frac{9\times 9+1}{9}$$

Ko te maha noa iti rawa atu o 2 me 3 ko 6. Me tahuri \frac{31}{2} me \frac{23}{3} ki te hautau me te tautūnga 6.

$$\frac{93}{6}+\frac{46}{6}-\frac{9\times 9+1}{9}$$

Tā te mea he rite te tauraro o \frac{93}{6} me \frac{46}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{93+46}{6}-\frac{9\times 9+1}{9}$$

Tāpirihia te 93 ki te 46, ka 139.

$$\frac{139}{6}-\frac{9\times 9+1}{9}$$

Whakareatia te 9 ki te 9, ka 81.

$$\frac{139}{6}-\frac{81+1}{9}$$

Tāpirihia te 81 ki te 1, ka 82.

$$\frac{139}{6}-\frac{82}{9}$$

Ko te maha noa iti rawa atu o 6 me 9 ko 18. Me tahuri \frac{139}{6} me \frac{82}{9} ki te hautau me te tautūnga 18.

$$\frac{417}{18}-\frac{164}{18}$$

Tā te mea he rite te tauraro o \frac{417}{18} me \frac{164}{18}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{417-164}{18}$$

Tangohia te 164 i te 417, ka 253.

$$\frac{253}{18}$$

Tauwehe

$$\frac{11 \cdot 23}{2 \cdot 3 ^ {2}} = 14\frac{1}{18} = 14.055555555555555$$
