д) 7$$\frac{4}{11}$$ - 5$$\frac{1}{9}$$ - 8$$\frac{10}{11}$$ + 2$$\frac{1}{3}$$ - 4$$\frac{2}{9}$$ + 3$$\frac{6}{11}$$ =

= $$\frac{81}{11} - \frac{46}{9} - \frac{98}{11} + \frac{7}{3} - \frac{38}{9} + \frac{39}{11}$$ =

= $$(\frac{81}{11} - \frac{98}{11} + \frac{39}{11}) + (- \frac{46}{9} - \frac{38}{9}) + \frac{7}{3}$$ =

= $$\frac{81 - 98 + 39}{11} - \frac{46 + 38}{9} + \frac{7}{3}$$ =

= $$\frac{22}{11} - \frac{84}{9} + \frac{7}{3}$$ =

= $$2 - \frac{28}{3} + \frac{7}{3}$$ =

= $$2 - \frac{28 - 7}{3}$$ =

= $$2 - \frac{21}{3}$$ =

= $$2 - 7 = -5$$

е) 5$$\frac{2}{22}$$ - 8$$\frac{3}{11}$$ - 7$$\frac{4}{13}$$ + 8$$\frac{3}{11}$$ + 7$$\frac{4}{13}$$ - 5$$\frac{1}{22}$$ =

= $$(\frac{112}{22} - \frac{111}{22}) + (- \frac{91}{11} + \frac{91}{11}) + (- \frac{95}{13} + \frac{95}{13})$$ =

= $$\frac{1}{22} + 0 + 0 = \frac{1}{22}$$
