[m]((12 \frac{8}{9}):(3 \frac{2}{9}) - (3 \frac{1}{2})) + (1 \frac{3}{4} - \frac{6}{10}) \cdot (1 \frac{7}{23}) = (\frac{116}{9} : \frac{29}{9} - \frac{7}{2}) + (\frac{7}{4} - \frac{3}{5}) \cdot \frac{30}{23} =[/m]
[m]= (\frac{116}{9} \cdot \frac{9}{29} - \frac{7}{2}) + (\frac{35}{20} - \frac{12}{20}) \cdot \frac{30}{23} = (\frac{116}{29} - \frac{7}{2}) + \frac{23}{20} \cdot \frac{30}{23} =[/m]
[m]= (4 - \frac{7}{2}) + \frac{30}{20} = \frac{1}{2} + \frac{3}{2} = 2[/m]
