Me whakarea te \frac{1}{2} ki te \frac{1}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{8}{\frac{1\times 1}{2\times 4}+\frac{3}{4}\times \frac{5}{2}}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 1}{2\times 4}.

$$\frac{8}{\frac{1}{8}+\frac{3}{4}\times \frac{5}{2}}$$

Me whakarea te \frac{3}{4} ki te \frac{5}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{8}{\frac{1}{8}+\frac{3\times 5}{4\times 2}}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 5}{4\times 2}.

$$\frac{8}{\frac{1}{8}+\frac{15}{8}}$$

Tā te mea he rite te tauraro o \frac{1}{8} me \frac{15}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{8}{\frac{1+15}{8}}$$

Tāpirihia te 1 ki te 15, ka 16.

$$\frac{8}{\frac{16}{8}}$$

Whakawehea te 16 ki te 8, kia riro ko 2.

$$\frac{8}{2}$$

Whakawehea te 8 ki te 2, kia riro ko 4.
