Passi tas-Soluzzjonijiet

Iddividi \frac{5\times 7+1}{7} b'\frac{2\times 4+1}{4} billi timmultiplika \frac{5\times 7+1}{7} bir-reċiproku ta' \frac{2\times 4+1}{4}.

$$\frac{\left(5\times 7+1\right)\times 4}{7\left(2\times 4+1\right)}$$

Immultiplika 5 u 7 biex tikseb 35.

$$\frac{\left(35+1\right)\times 4}{7\left(2\times 4+1\right)}$$

Żid 35 u 1 biex tikseb 36.

$$\frac{36\times 4}{7\left(2\times 4+1\right)}$$

Immultiplika 36 u 4 biex tikseb 144.

$$\frac{144}{7\left(2\times 4+1\right)}$$

Immultiplika 2 u 4 biex tikseb 8.

$$\frac{144}{7\left(8+1\right)}$$

Żid 8 u 1 biex tikseb 9.

$$\frac{144}{7\times 9}$$

Immultiplika 7 u 9 biex tikseb 63.

$$\frac{144}{63}$$

Naqqas il-frazzjoni \frac{144}{63} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 9.
