Passi tas-Soluzzjonijiet

Iddividi \frac{1\times 4+2}{4} b'\frac{7\times 3+1}{3} billi timmultiplika \frac{1\times 4+2}{4} bir-reċiproku ta' \frac{7\times 3+1}{3}.

$$\frac{\left(1\times 4+2\right)\times 3}{4\left(7\times 3+1\right)}$$

Immultiplika 1 u 4 biex tikseb 4.

$$\frac{\left(4+2\right)\times 3}{4\left(7\times 3+1\right)}$$

Żid 4 u 2 biex tikseb 6.

$$\frac{6\times 3}{4\left(7\times 3+1\right)}$$

Immultiplika 6 u 3 biex tikseb 18.

$$\frac{18}{4\left(7\times 3+1\right)}$$

Immultiplika 7 u 3 biex tikseb 21.

$$\frac{18}{4\left(21+1\right)}$$

Żid 21 u 1 biex tikseb 22.

$$\frac{18}{4\times 22}$$

Immultiplika 4 u 22 biex tikseb 88.

$$\frac{18}{88}$$

Naqqas il-frazzjoni \frac{18}{88} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.
