Whakareatia te 2 ki te 1.125, ka 2.25.

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

Tangohia te 3 i te 2.25, ka -0.75.

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

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

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

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

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

Whakareatia te 4 ki te 1.125, ka 4.5.

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

Whakareatia te 4.5 ki te 5, ka 22.5.

$$-20=\frac{10}{22.5}$$

Whakarohaina te \frac{10}{22.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$-20=\frac{100}{225}$$

Whakahekea te hautanga \frac{100}{225} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$-20=\frac{4}{9}$$

Me tahuri te -20 ki te hautau -\frac{180}{9}.

$$-\frac{180}{9}=\frac{4}{9}$$

Whakatauritea te -\frac{180}{9} me te \frac{4}{9}.
