Me whakakore tahi te 5 i te taurunga me te tauraro.

$$\frac{13\left(9\times 65-300\right)^{2}}{3\times 20\times 45\times 50}=6635$$

Whakareatia te 9 ki te 65, ka 585.

$$\frac{13\left(585-300\right)^{2}}{3\times 20\times 45\times 50}=6635$$

Tangohia te 300 i te 585, ka 285.

$$\frac{13\times 285^{2}}{3\times 20\times 45\times 50}=6635$$

Tātaihia te 285 mā te pū o 2, kia riro ko 81225.

$$\frac{13\times 81225}{3\times 20\times 45\times 50}=6635$$

Whakareatia te 13 ki te 81225, ka 1055925.

$$\frac{1055925}{3\times 20\times 45\times 50}=6635$$

Whakareatia te 3 ki te 20, ka 60.

$$\frac{1055925}{60\times 45\times 50}=6635$$

Whakareatia te 60 ki te 45, ka 2700.

$$\frac{1055925}{2700\times 50}=6635$$

Whakareatia te 2700 ki te 50, ka 135000.

$$\frac{1055925}{135000}=6635$$

Whakahekea te hautanga \frac{1055925}{135000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 225.

$$\frac{4693}{600}=6635$$

Me tahuri te 6635 ki te hautau \frac{3981000}{600}.

$$\frac{4693}{600}=\frac{3981000}{600}$$

Whakatauritea te \frac{4693}{600} me te \frac{3981000}{600}.
