Ko te maha noa iti rawa atu o 25 me 16 ko 400. Me tahuri \frac{2}{25} me \frac{5}{16} ki te hautau me te tautūnga 400.

$$\frac{\frac{8}{5}}{\frac{32}{400}-\frac{125}{400}}=3$$

Tā te mea he rite te tauraro o \frac{32}{400} me \frac{125}{400}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{8}{5}}{\frac{32-125}{400}}=3$$

Tangohia te 125 i te 32, ka -93.

$$\frac{\frac{8}{5}}{-\frac{93}{400}}=3$$

Whakawehe \frac{8}{5} ki te -\frac{93}{400} mā te whakarea \frac{8}{5} ki te tau huripoki o -\frac{93}{400}.

$$\frac{8}{5}\left(-\frac{400}{93}\right)=3$$

Me whakarea te \frac{8}{5} ki te -\frac{400}{93} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{8\left(-400\right)}{5\times 93}=3$$

Mahia ngā whakarea i roto i te hautanga \frac{8\left(-400\right)}{5\times 93}.

$$\frac{-3200}{465}=3$$

Whakahekea te hautanga \frac{-3200}{465} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$-\frac{640}{93}=3$$

Me tahuri te 3 ki te hautau \frac{279}{93}.

$$-\frac{640}{93}=\frac{279}{93}$$

Whakatauritea te -\frac{640}{93} me te \frac{279}{93}.

$$\text{false}$$
