Passi tas-Soluzzjonijiet

Iddividi \frac{2\times 7+2}{7} b'\frac{3\times 5+1}{5} billi timmultiplika \frac{2\times 7+2}{7} bir-reċiproku ta' \frac{3\times 5+1}{5}.

$$\frac{\left(2\times 7+2\right)\times 5}{7\left(3\times 5+1\right)}$$

Immultiplika 2 u 7 biex tikseb 14.

$$\frac{\left(14+2\right)\times 5}{7\left(3\times 5+1\right)}$$

Żid 14 u 2 biex tikseb 16.

$$\frac{16\times 5}{7\left(3\times 5+1\right)}$$

Immultiplika 16 u 5 biex tikseb 80.

$$\frac{80}{7\left(3\times 5+1\right)}$$

Immultiplika 3 u 5 biex tikseb 15.

$$\frac{80}{7\left(15+1\right)}$$

Żid 15 u 1 biex tikseb 16.

$$\frac{80}{7\times 16}$$

Immultiplika 7 u 16 biex tikseb 112.

$$\frac{80}{112}$$

Naqqas il-frazzjoni \frac{80}{112} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 16.
