Vypočítej:
\( \large \left( {\Large \frac{1}{2}\large + \Large \frac{1}{3}\large } \right) \cdot \left( {\Large \frac{2}{5}\large - \Large \frac{3}{4}\large } \right) \)
\( \large =- \Large \frac{7}{24}\large \)
\( \large = \Large \frac{7}{24}\large \)
\( \large =- \Large \frac{7}{20}\large \)
\( \large =- \Large \frac{5}{24}\large \)
