(`3` - `2/3` + `4/3`) : (`2`$\frac{1}{3}$ - `2,5`)^{2}$
= ($\frac{9}{3}$ - $\frac{2}{3}$ + $\frac{4}{3}$) : ($\frac{7}{3}$ - $\frac{25}{10}$)^{2}
= ($\frac{7}{3}$ + $\frac{4}{3}$) : ($\frac{70}{30}$ - $\frac{75}{30}$ )^{2}
= $\frac{11}{3}$ : ($\frac{-1}{6}$)^{2}
= $\frac{11}{3}$ : $\frac{1}{36}$
= $\frac{11}{3}$ x `36`
= `132`
