Пошаговое объяснение:

$1) \frac{9}{10} +\frac{1^{/2} }{5} = \frac{9}{10} + \frac{2}{10} = \frac{11}{10} = 1\frac{1}{10} \\\\2) \frac{4^{/3} }{5} + \frac{2}{15} = \frac{12}{15} + \frac{2}{15} = \frac{14}{15} \\\\3) \frac{3^{/2} }{7} + \frac{5}{14} = \frac{6}{14} + \frac{5}{14} = \frac{11}{14} \\\\4)\frac{5}{12} + \frac{1^{/2} }{6} = \frac{5}{12} + \frac{2}{12} = \frac{7}{12} \\\\5) \frac{5}{18} + \frac{2^{/2} }{9} = \frac{5}{18} + \frac{4}{18} = \frac{9}{18} = \frac{1}{2}$

$6)\frac{11}{16} - \frac{1^{/4} }{4} = \frac{11}{16} - \frac{4}{16} = \frac{7}{16}\\\\7) \frac{4^{/8} }{5} - \frac{5^{/5} }{8} = \frac{32}{40} - \frac{25}{40} = \frac{7}{40}$
