Ngā Upane Otinga

Tāpirihia te 7 ki te 1, ka 8.

$$7+\frac{8\left(8+3\times 4\right)}{3+4\times 9}$$

Whakareatia te 3 ki te 4, ka 12.

$$7+\frac{8\left(8+12\right)}{3+4\times 9}$$

Tāpirihia te 8 ki te 12, ka 20.

$$7+\frac{8\times 20}{3+4\times 9}$$

Whakareatia te 8 ki te 20, ka 160.

$$7+\frac{160}{3+4\times 9}$$

Whakareatia te 4 ki te 9, ka 36.

$$7+\frac{160}{3+36}$$

Tāpirihia te 3 ki te 36, ka 39.

$$7+\frac{160}{39}$$

Me tahuri te 7 ki te hautau \frac{273}{39}.

$$\frac{273}{39}+\frac{160}{39}$$

Tā te mea he rite te tauraro o \frac{273}{39} me \frac{160}{39}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{273+160}{39}$$

Tāpirihia te 273 ki te 160, ka 433.

$$\frac{433}{39}$$

Tauwehe

$$\frac{433}{3 \cdot 13} = 11\frac{4}{39} = 11.102564102564102$$
