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