  1. а) \(\frac{5}{6}+\frac{7}{16}=\frac{40}{48}+\frac{21}{48}=\frac{61}{48}=1\frac{13}{48}\).
  2. б) \(\frac{7}{30}+\frac{1}{12}=\frac{14}{60}+\frac{5}{60}=\frac{19}{60}\).
  3. в) \(\frac{5}{9}-\frac{5}{18}=\frac{10}{18}-\frac{5}{18}=\frac{5}{18}\).
  4. г) \(\frac{5}{16}-\frac{5}{48}=\frac{15}{48}-\frac{5}{48}=\frac{5}{24}\).
  5. д) \(4\frac{5}{8}-2\frac{5}{9}=2+\frac{5}{8}-\frac{5}{9}=2+\frac{45-40}{72}=2\frac{5}{72}\).
  6. е) \(16\frac{4}{9}-1\frac{7}{9}=15-\frac{3}{9}=14\frac{2}{3}\).
  7. ё) \(12\frac{2}{15}-2\frac{1}{5}=12\frac{2}{15}-2\frac{3}{15}=10\frac{14}{15}\).
  8. ж) \(3\frac{3}{8}+1\frac{1}{8}=4\frac{4}{8}=4\frac{1}{2}\).
  9. з) \(2\frac{3}{5}+10\frac{2}{5}=12+1=13\).
