Из данных равенств выберите неверное.
1) 5 ∙ \(\frac{3}{4}\) = \(\frac{3}{4}\) ∙ 5
2) \( $\frac{7}{8}$ \+ 5 \) ∙ \(\frac{3}{4}\) = \(\frac{7}{8}\) + 5 ∙ \(\frac{3}{4}\)
3) \( $\frac{4}{9}$ ∙ $\frac{24}{11}$ \) ∙ 8 = 8 ∙ \( $\frac{4}{9}$ ∙ $\frac{24}{11}$ \)
4) \(\frac{5}{7}\) ∙ \( 6 \- $\frac{3}{4}$ \) = 6 ∙ \(\frac{5}{7}\) - \(\frac{5}{7}\) ∙ \(\frac{3}{4}\)
