Whakareatia te 2 ki te 1.125, ka 2.25.

$$\frac{15}{2.25-3}=\frac{10}{4\times 1.125-5}$$

Tangohia te 3 i te 2.25, ka -0.75.

$$\frac{15}{-0.75}=\frac{10}{4\times 1.125-5}$$

Whakarohaina te \frac{15}{-0.75} mā te whakarea i te taurunga me te tauraro ki te 100.

$$\frac{1500}{-75}=\frac{10}{4\times 1.125-5}$$

Whakawehea te 1500 ki te -75, kia riro ko -20.

$$-20=\frac{10}{4\times 1.125-5}$$

Whakareatia te 4 ki te 1.125, ka 4.5.

$$-20=\frac{10}{4.5-5}$$

Tangohia te 5 i te 4.5, ka -0.5.

$$-20=\frac{10}{-0.5}$$

Whakarohaina te \frac{10}{-0.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$-20=\frac{100}{-5}$$

Whakawehea te 100 ki te -5, kia riro ko -20.

$$-20=-20$$

Whakatauritea te -20 me te -20.
