Ngā Upane Otinga

Whakareatia te 2 ki te 12, ka 24.

$$\frac{\frac{24+1}{12}}{-\frac{2\times 16+3}{16}}$$

Tāpirihia te 24 ki te 1, ka 25.

$$\frac{\frac{25}{12}}{-\frac{2\times 16+3}{16}}$$

Whakareatia te 2 ki te 16, ka 32.

$$\frac{\frac{25}{12}}{-\frac{32+3}{16}}$$

Tāpirihia te 32 ki te 3, ka 35.

$$\frac{\frac{25}{12}}{-\frac{35}{16}}$$

Whakawehe \frac{25}{12} ki te -\frac{35}{16} mā te whakarea \frac{25}{12} ki te tau huripoki o -\frac{35}{16}.

$$\frac{25}{12}\left(-\frac{16}{35}\right)$$

Me whakarea te \frac{25}{12} ki te -\frac{16}{35} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25\left(-16\right)}{12\times 35}$$

Mahia ngā whakarea i roto i te hautanga \frac{25\left(-16\right)}{12\times 35}.

$$\frac{-400}{420}$$

Whakahekea te hautanga \frac{-400}{420} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$-\frac{20}{21}$$

Tauwehe
