Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$\frac{3}{5}-7=3\times 7-5\times 7$$

Me tahuri te 7 ki te hautau \frac{35}{5}.

$$\frac{3}{5}-\frac{35}{5}=3\times 7-5\times 7$$

Tā te mea he rite te tauraro o \frac{3}{5} me \frac{35}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3-35}{5}=3\times 7-5\times 7$$

Tangohia te 35 i te 3, ka -32.

$$-\frac{32}{5}=3\times 7-5\times 7$$

Whakareatia te 3 ki te 7, ka 21.

$$-\frac{32}{5}=21-5\times 7$$

Whakareatia te 5 ki te 7, ka 35.

$$-\frac{32}{5}=21-35$$

Tangohia te 35 i te 21, ka -14.

$$-\frac{32}{5}=-14$$

Me tahuri te -14 ki te hautau -\frac{70}{5}.

$$-\frac{32}{5}=-\frac{70}{5}$$

Whakatauritea te -\frac{32}{5} me te -\frac{70}{5}.
