$$10+\frac{1}{6}$$

Ikkonverti 10 fi frazzjoni \frac{60}{6}.

$$\frac{60}{6}+\frac{1}{6}$$

Billi \frac{60}{6} u \frac{1}{6} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{60+1}{6}$$

Żid 60 u 1 biex tikseb 61.

$$\frac{61}{6}$$

Fattur

$$\frac{61}{2 \cdot 3} = 10\frac{1}{6} = 10.166666666666666$$
