Me whakarea te \frac{4}{25} ki te \frac{3}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{4\times 3}{25\times 4}-\frac{1}{50}$$

Me whakakore tahi te 4 i te taurunga me te tauraro.

$$\frac{3}{25}-\frac{1}{50}$$

Ko te maha noa iti rawa atu o 25 me 50 ko 50. Me tahuri \frac{3}{25} me \frac{1}{50} ki te hautau me te tautūnga 50.

$$\frac{6}{50}-\frac{1}{50}$$

Tā te mea he rite te tauraro o \frac{6}{50} me \frac{1}{50}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{6-1}{50}$$

Tangohia te 1 i te 6, ka 5.

$$\frac{5}{50}$$

Whakahekea te hautanga \frac{5}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{1}{10}$$

Tauwehe

$$\frac{1}{2 \cdot 5} = 0.1$$
