Answer 1

$2 \frac{1}{3} \div x - 1 \frac{1}{6} = 1 \frac{5}{9} \\ 2 \frac{1}{3} \div x - 1 \frac{1}{6} = 1 \frac{5}{9} \\ \frac{7}{3} \times \frac{1}{x} - \frac{7}{6} = \frac{14}{9} \\ \frac{7}{3x} - \frac{7}{6} = \frac{14}{9} \\ \frac{7}{3x} = \frac{14}{9} + \frac{7}{6} \\ \frac{7}{3x} = \frac{49}{18} \\ 147x = 126 \\ x = \frac{6}{7}$

$\frac{1}{3} x + \frac{1}{4} x + \frac{1}{5} x = 1 \frac{19}{75} \\ \frac{1}{3} x + \frac{1}{4} x + \frac{1}{5} x = \frac{94}{75} \\ 100x + 70x + 60x = 376 \\ 235x = 376 \\ x = \frac{8}{5}$
