Ngā Upane Otinga

Tuhia te \frac{\frac{1}{2}}{4} hei hautanga kotahi.

$$\frac{\frac{1}{2\times 4}+20}{\frac{1}{2}\times 4+20}$$

Whakareatia te 2 ki te 4, ka 8.

$$\frac{\frac{1}{8}+20}{\frac{1}{2}\times 4+20}$$

Me tahuri te 20 ki te hautau \frac{160}{8}.

$$\frac{\frac{1}{8}+\frac{160}{8}}{\frac{1}{2}\times 4+20}$$

Tā te mea he rite te tauraro o \frac{1}{8} me \frac{160}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{1+160}{8}}{\frac{1}{2}\times 4+20}$$

Tāpirihia te 1 ki te 160, ka 161.

$$\frac{\frac{161}{8}}{\frac{1}{2}\times 4+20}$$

Whakareatia te \frac{1}{2} ki te 4, ka \frac{4}{2}.

$$\frac{\frac{161}{8}}{\frac{4}{2}+20}$$

Whakawehea te 4 ki te 2, kia riro ko 2.

$$\frac{\frac{161}{8}}{2+20}$$

Tāpirihia te 2 ki te 20, ka 22.

$$\frac{\frac{161}{8}}{22}$$

Tuhia te \frac{\frac{161}{8}}{22} hei hautanga kotahi.

$$\frac{161}{8\times 22}$$

Whakareatia te 8 ki te 22, ka 176.

$$\frac{161}{176}$$

Tauwehe

$$\frac{7 \cdot 23}{2 ^ {4} \cdot 11} = 0.9147727272727273$$
