Whakareatia te 3 ki te 7, ka 21.

$$\frac{21+4}{7}\times \frac{1\times 5+2}{5}\times 125$$

Tāpirihia te 21 ki te 4, ka 25.

$$\frac{25}{7}\times \frac{1\times 5+2}{5}\times 125$$

Whakareatia te 1 ki te 5, ka 5.

$$\frac{25}{7}\times \frac{5+2}{5}\times 125$$

Tāpirihia te 5 ki te 2, ka 7.

$$\frac{25}{7}\times \frac{7}{5}\times 125$$

Me whakarea te \frac{25}{7} ki te \frac{7}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25\times 7}{7\times 5}\times 125$$

Me whakakore tahi te 7 i te taurunga me te tauraro.
