Решение:

a) \( \frac{3}{8} + \frac{4}{8} = \frac{3+4}{8} = \frac{7}{8} \)

б) \( \frac{1}{5} + \frac{3}{3} = \frac{1}{5} + 1 = \frac{1}{5} + \frac{5}{5} = \frac{1+5}{5} = \frac{6}{5} = 1 \frac{1}{5} \)

в) \( \frac{4}{18} + \frac{13}{18} = \frac{4+13}{18} = \frac{17}{18} \)

г) \( \frac{7}{8} + \frac{9}{9} = \frac{7}{8} + 1 = \frac{7}{8} + \frac{8}{8} = \frac{7+8}{8} = \frac{15}{8} = 1 \frac{7}{8} \)

д) \( \frac{1}{4} + \frac{7}{7} = \frac{1}{4} + 1 = \frac{1}{4} + \frac{4}{4} = \frac{1+4}{4} = \frac{5}{4} = 1 \frac{1}{4} \)

е) \( \frac{6}{11} + \frac{5}{11} = \frac{6+5}{11} = \frac{11}{11} = 1 \)

ж) \( \frac{6}{10} + \frac{3}{10} = \frac{6+3}{10} = \frac{9}{10} \)

з) \( \frac{4}{56} + \frac{27}{56} = \frac{4+27}{56} = \frac{31}{56} \)

и) \( \frac{14}{32} + \frac{45}{32} = \frac{14+45}{32} = \frac{59}{32} = 1 \frac{27}{32} \)

к) \( \frac{12}{89} + \frac{67}{89} = \frac{12+67}{89} = \frac{79}{89} \)
