Whakarohaina te \frac{0.027}{0.003} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$\left(\frac{27}{3}+\frac{0.0016}{0.002}\right)\times \frac{1}{10}$$

Whakawehea te 27 ki te 3, kia riro ko 9.

$$\left(9+\frac{0.0016}{0.002}\right)\times \frac{1}{10}$$

Whakarohaina te \frac{0.0016}{0.002} mā te whakarea i te taurunga me te tauraro ki te 10000.

$$\left(9+\frac{16}{20}\right)\times \frac{1}{10}$$

Whakahekea te hautanga \frac{16}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\left(9+\frac{4}{5}\right)\times \frac{1}{10}$$

Me tahuri te 9 ki te hautau \frac{45}{5}.

$$\left(\frac{45}{5}+\frac{4}{5}\right)\times \frac{1}{10}$$

Tā te mea he rite te tauraro o \frac{45}{5} me \frac{4}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{45+4}{5}\times \frac{1}{10}$$

Tāpirihia te 45 ki te 4, ka 49.

$$\frac{49}{5}\times \frac{1}{10}$$

Me whakarea te \frac{49}{5} ki te \frac{1}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{49\times 1}{5\times 10}$$

Mahia ngā whakarea i roto i te hautanga \frac{49\times 1}{5\times 10}.

$$\frac{49}{50}$$

Tauwehe

$$\frac{7 ^ {2}}{2 \cdot 5 ^ {2}} = 0.98$$
