Ngā Upane Otinga

Whakarohaina te \frac{9}{-0.12} mā te whakarea i te taurunga me te tauraro ki te 100.

$$\frac{900}{-12}-\frac{9}{5\left(-0.12\right)}$$

Whakawehea te 900 ki te -12, kia riro ko -75.

$$-75-\frac{9}{5\left(-0.12\right)}$$

Whakareatia te 5 ki te -0.12, ka -0.6.

$$-75-\frac{9}{-0.6}$$

Whakarohaina te \frac{9}{-0.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$-75-\frac{90}{-6}$$

Whakawehea te 90 ki te -6, kia riro ko -15.

$$-75-\left(-15\right)$$

Ko te tauaro o -15 ko 15.

$$-75+15$$

Tāpirihia te -75 ki te 15, ka -60.

$$-60$$
