[tex] \frac{2}{3} - \frac{1}{7} = \frac{14}{21} - \frac{3}{21} = \frac{11}{21} \\ \\ - \frac{11}{4} - \frac{3}{2} + \frac{17}{3} =- \frac{33}{12} - \frac{18}{12} + \frac{68}{12} =- \frac{51}{12} + \frac{68}{12} = \frac{17}{12} \\ \\ \frac{6}{11} - \frac{23}{22} + \frac{5}{2} = \frac{12}{22} - \frac{23}{22} + \frac{55}{22} =- \frac{11}{22} + \frac{55}{22} = \frac{44}{22} = 2[/tex]
