Ngā Upane Otinga

Me tahuri ki tau ā-ira 0.125 ki te hautau \frac{125}{1000}. Whakahekea te hautanga \frac{125}{1000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 125.

$$-\frac{3}{7}\times \frac{1}{8}\left(-\frac{2\times 3+1}{3}\right)\left(-8\right)$$

Me whakarea te -\frac{3}{7} ki te \frac{1}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-3}{7\times 8}\left(-\frac{2\times 3+1}{3}\right)\left(-8\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{-3}{7\times 8}.

$$\frac{-3}{56}\left(-\frac{2\times 3+1}{3}\right)\left(-8\right)$$

Ka taea te hautanga \frac{-3}{56} te tuhi anō ko -\frac{3}{56} mā te tango i te tohu tōraro.

$$-\frac{3}{56}\left(-\frac{2\times 3+1}{3}\right)\left(-8\right)$$

Whakareatia te 2 ki te 3, ka 6.

$$-\frac{3}{56}\left(-\frac{6+1}{3}\right)\left(-8\right)$$

Tāpirihia te 6 ki te 1, ka 7.

$$-\frac{3}{56}\left(-\frac{7}{3}\right)\left(-8\right)$$

Me whakarea te -\frac{3}{56} ki te -\frac{7}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-3\left(-7\right)}{56\times 3}\left(-8\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{-3\left(-7\right)}{56\times 3}.

$$\frac{21}{168}\left(-8\right)$$

Whakahekea te hautanga \frac{21}{168} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 21.

$$\frac{1}{8}\left(-8\right)$$

Whakareatia te \frac{1}{8} ki te -8, ka \frac{-8}{8}.

$$\frac{-8}{8}$$

Whakawehea te -8 ki te 8, kia riro ko -1.
