Żid 49 u 3 biex tikseb 52.

$$0+\frac{3}{4}\times \frac{52}{7}+75\times \frac{1}{7}$$

Immultiplika \frac{3}{4} b'\frac{52}{7} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$0+\frac{3\times 52}{4\times 7}+75\times \frac{1}{7}$$

Agħmel il-multiplikazzjonijiet fil-frazzjoni \frac{3\times 52}{4\times 7}.

$$0+\frac{156}{28}+75\times \frac{1}{7}$$

Naqqas il-frazzjoni \frac{156}{28} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 4.

$$0+\frac{39}{7}+75\times \frac{1}{7}$$

Żid 0 u \frac{39}{7} biex tikseb \frac{39}{7}.

$$\frac{39}{7}+75\times \frac{1}{7}$$

Immultiplika 75 u \frac{1}{7} biex tikseb \frac{75}{7}.

$$\frac{39}{7}+\frac{75}{7}$$

Billi \frac{39}{7} u \frac{75}{7} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{39+75}{7}$$

Żid 39 u 75 biex tikseb 114.

$$\frac{114}{7}$$

Fattur

$$\frac{2 \cdot 3 \cdot 19}{7} = 16\frac{2}{7} = 16.285714285714285$$
