Passi tas-Soluzzjonijiet

Naqqas \frac{1}{3} minn 1 biex tikseb \frac{2}{3}.

$$\frac{\left(\frac{2}{3}\right)^{2}+1-\frac{1}{9}}{2-\frac{1}{3}}$$

Ikkalkula \frac{2}{3} bil-power ta' 2 u tikseb \frac{4}{9}.

$$\frac{\frac{4}{9}+1-\frac{1}{9}}{2-\frac{1}{3}}$$

Żid \frac{4}{9} u 1 biex tikseb \frac{13}{9}.

$$\frac{\frac{13}{9}-\frac{1}{9}}{2-\frac{1}{3}}$$

Naqqas \frac{1}{9} minn \frac{13}{9} biex tikseb \frac{4}{3}.

$$\frac{\frac{4}{3}}{2-\frac{1}{3}}$$

Naqqas \frac{1}{3} minn 2 biex tikseb \frac{5}{3}.

$$\frac{\frac{4}{3}}{\frac{5}{3}}$$

Iddividi \frac{4}{3} b'\frac{5}{3} billi timmultiplika \frac{4}{3} bir-reċiproku ta' \frac{5}{3}.

$$\frac{4}{3}\times \frac{3}{5}$$

Immultiplika \frac{4}{3} u \frac{3}{5} biex tikseb \frac{4}{5}.

$$\frac{4}{5}$$

Fattur

$$\frac{2 ^ {2}}{5} = 0.8$$
