Me whakakore tahi te 3\times 9 i te taurunga me te tauraro.

$$\frac{7\times 685\times 10^{3}}{69\times 277}$$

Whakareatia te 7 ki te 685, ka 4795.

$$\frac{4795\times 10^{3}}{69\times 277}$$

Tātaihia te 10 mā te pū o 3, kia riro ko 1000.

$$\frac{4795\times 1000}{69\times 277}$$

Whakareatia te 4795 ki te 1000, ka 4795000.

$$\frac{4795000}{69\times 277}$$

Whakareatia te 69 ki te 277, ka 19113.

$$\frac{4795000}{19113}$$

Tauwehe

$$\frac{2 ^ {3} \cdot 5 ^ {4} \cdot 7 \cdot 137}{3 \cdot 23 \cdot 277} = 250\frac{16750}{19113} = 250.87636687071625$$
