Решите задачу:

$1) \frac{2}{7} + \frac{1}{7} = \frac{2+1}{7} = \frac{3}{7}$

$2) \frac{9}{14} - \frac{5}{14} = \frac{9-5}{14} = \frac{4}{14} = \frac{2}{7}$

$3) \frac{5}{6} - \frac{1}{6} = \frac{5-1}{6} = \frac{4}{6} = \frac{2}{3}$

$4) \frac{5}{9} + \frac{2}{9} = \frac{5+2}{9} = \frac{7}{9}$

$5) \frac{13}{20} + \frac{11}{20} = \frac{24}{20} = 1 \frac{1}{5}$

$6) \frac{17}{32} - \frac{15}{32} = \frac{17-15}{32} = \frac{2}{32} = \frac{1}{16}$

$7) \frac{41}{100} - \frac{33}{100} = \frac{41-33}{100} = \frac{8}{100} = \frac{2}{25}$

$8) \frac{8}{99} + \frac{2}{99} = \frac{8+2}{99} = \frac{10}{99}$
