$\frac{7}{18} + \frac{5}{18} = \frac{7+5}{18} = \frac{12}{18} = \frac{2}{3}$

$\frac{11}{24} + \frac{8}{24} = \frac{11+8}{24} = \frac{19}{24}$

$\frac{23}{47} - \frac{14}{47} = \frac{23-14}{47} = \frac{9}{47}$

$\frac{31}{58} - \frac{16}{58} = \frac{31-16}{58} = \frac{15}{58}$

$\frac{3}{29} + \frac{6}{29} - \frac{8}{29} = \frac{3+6-8}{29} = \frac{1}{29}$

$\frac{29}{64} - \frac{14}{64} - \frac{9}{64} = \frac{29-14-9}{64} = \frac{6}{64} = \frac{3}{32}$
