Answer 1

$\frac{3}{17} + \frac{8}{51} = \frac{9}{51} + \frac{8}{51} = \frac{17}{51} = \frac{1}{3}$

$\frac{9}{20} + \frac{1}{5} = \frac{9}{20} + \frac{4}{20} = \frac{13}{20}$

$\frac{2}{6} - \frac{1}{8} = \frac{16}{48} - \frac{6}{48} = \frac{10}{48} = \frac{5}{24}$

$\frac{7}{24} + \frac{3}{6} = \frac{7}{24} + \frac{12}{24} = \frac{19}{24}$

$\frac{5}{32} + \frac{1}{16} = \frac{5}{32} + \frac{2}{32} = \frac{7}{32}$

$\frac{7}{27} - \frac{3}{81} = \frac{21}{81} - \frac{3}{81} = \frac{18}{81} = \frac{2}{9}$

$\frac{3}{5} - \frac{7}{60} = \frac{36}{60} - \frac{7}{60} = \frac{29}{60}$

$\frac{1}{2} - \frac{1}{3} = \frac{3}{6} - \frac{2}{6} = \frac{1}{6}$
