$$5$$

Ngā Upane Otinga

Whakareatia te 1 ki te 3, ka 3.

$$\frac{-\frac{3+2}{3}}{\frac{5}{6}}\left(-\frac{2\times 2+1}{2}\right)$$

Tāpirihia te 3 ki te 2, ka 5.

$$\frac{-\frac{5}{3}}{\frac{5}{6}}\left(-\frac{2\times 2+1}{2}\right)$$

Whakawehe -\frac{5}{3} ki te \frac{5}{6} mā te whakarea -\frac{5}{3} ki te tau huripoki o \frac{5}{6}.

$$-\frac{5}{3}\times \frac{6}{5}\left(-\frac{2\times 2+1}{2}\right)$$

Me whakarea te -\frac{5}{3} ki te \frac{6}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-5\times 6}{3\times 5}\left(-\frac{2\times 2+1}{2}\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{-5\times 6}{3\times 5}.

$$\frac{-30}{15}\left(-\frac{2\times 2+1}{2}\right)$$

Whakawehea te -30 ki te 15, kia riro ko -2.

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

Whakareatia te 2 ki te 2, ka 4.

$$-2\left(-\frac{4+1}{2}\right)$$

Tāpirihia te 4 ki te 1, ka 5.

$$-2\left(-\frac{5}{2}\right)$$

Whakareatia -2 ki te -\frac{5}{2}.
