Kwalunkwe ħaġa diviża b'wieħed tagħti riżultat tagħha stess.

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

Ikkonverti 7 fi frazzjoni \frac{35}{5}.

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

Billi \frac{3}{5} u \frac{35}{5} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

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

Naqqas 35 minn 3 biex tikseb -32.

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

Immultiplika 3 u 7 biex tikseb 21.

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

Immultiplika 5 u 7 biex tikseb 35.

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

Naqqas 35 minn 21 biex tikseb -14.

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

Ikkonverti -14 fi frazzjoni -\frac{70}{5}.

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

Qabbel -\frac{32}{5} u -\frac{70}{5}.
