Гость[latex] \frac{3}{4} + \frac{3}{4} * \frac{2}{3} + \frac{1}{3} =\frac{15}{12}[/latex]
[latex] \frac {3}{4} * \frac{2}{3} = \frac{3*2}{4*3} = \frac{6}{12} =\frac{1}{6}[/latex]
[latex] \frac {3}{4}+\frac{1}{6} = \frac{9}{12} + \frac{2}{12} = \frac{11}{12}[/latex]
[latex] \frac{11}{12} + \frac{1}{3} = \frac{11}{12} + \frac{4}{12} =\frac{15}{12}[/latex]
