Passi tas-Soluzzjonijiet

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

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

Immultiplika 2 u 2 biex tikseb 4.

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

Żid 4 u 1 biex tikseb 5.

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

Immultiplika 5 u 3 biex tikseb 15.

$$\frac{15}{2\left(3\times 3+2\right)}$$

Immultiplika 3 u 3 biex tikseb 9.

$$\frac{15}{2\left(9+2\right)}$$

Żid 9 u 2 biex tikseb 11.

$$\frac{15}{2\times 11}$$

Immultiplika 2 u 11 biex tikseb 22.

$$\frac{15}{22}$$

Fattur

$$\frac{3 \cdot 5}{2 \cdot 11} = 0.6818181818181818$$
