Пошаговое объяснение:
5.
[tex]1)\frac{7}{11} - \frac{1}{3} = \frac{21 - 11}{33} = \frac{10}{33} [/tex]
[tex]2) \frac{7}{11} + \frac{10}{33} = \frac{21 + 10}{33} = \frac{31}{33} [/tex]
[tex]3) 1 - \frac{31}{33} = \frac{2}{33}[/tex]
6.
[tex] (\frac{x}{9} < \frac{22}{45}) = (\frac{5x}{45} < \frac{22}{45}) [/tex]
[tex] \frac{5(x = 4)}{45} < \frac{22}{45} [/tex]
[tex] \frac{5(x = 5)}{45} > \frac{22}{45}[/tex]
