1. Вычислите: а) \(4\frac{1}{12}+1\frac{1}{6}\); б) \(2\frac{3}{5}+3\frac{1}{3}\); в) \(5\frac{14}{25}+2\frac{7}{15}\); г) \(7\frac{3}{10}-2\frac{4}{15}\); д) \(4\frac{5}{8}-2\frac{1}{3}\); е) \(5\frac{3}{4}-2\frac{4}{5}\).

а) \(4\frac{1}{12}+1\frac{1}{6}=5+\frac{1}{12}+\frac{2}{12}=5\frac{1}{4}\).

б) \(2\frac{3}{5}+3\frac{1}{3}=5+\frac{9}{15}+\frac{5}{15}=5\frac{14}{15}\).

в) \(5\frac{14}{25}+2\frac{7}{15}=7+\frac{42}{75}+\frac{35}{75}=8\frac{2}{25}\).

г) \(7\frac{3}{10}-2\frac{4}{15}=5+\frac{9}{30}-\frac{8}{30}=5\frac{1}{30}\).

д) \(4\frac{5}{8}-2\frac{1}{3}=2+\frac{15}{24}-\frac{8}{24}=2\frac{7}{24}\).

е) \(5\frac{3}{4}-2\frac{4}{5}=2+\frac{15}{20}-\frac{16}{20}=2\frac{19}{20}\).

Ответ: а) \(5\frac{1}{4}\); б) \(5\frac{14}{15}\); в) \(8\frac{2}{25}\); г) \(5\frac{1}{30}\); д) \(2\frac{7}{24}\); е) \(2\frac{19}{20}\).
