Ngā Upane Otinga

Whakareatia te 1 ki te 4, ka 4.

$$\frac{4+1}{4}\times 9+\frac{3}{4}\times 9$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{5}{4}\times 9+\frac{3}{4}\times 9$$

Tuhia te \frac{5}{4}\times 9 hei hautanga kotahi.

$$\frac{5\times 9}{4}+\frac{3}{4}\times 9$$

Whakareatia te 5 ki te 9, ka 45.

$$\frac{45}{4}+\frac{3}{4}\times 9$$

Tuhia te \frac{3}{4}\times 9 hei hautanga kotahi.

$$\frac{45}{4}+\frac{3\times 9}{4}$$

Whakareatia te 3 ki te 9, ka 27.

$$\frac{45}{4}+\frac{27}{4}$$

Tā te mea he rite te tauraro o \frac{45}{4} me \frac{27}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{45+27}{4}$$

Tāpirihia te 45 ki te 27, ka 72.

$$\frac{72}{4}$$

Whakawehea te 72 ki te 4, kia riro ko 18.
