Ответ:

а) \(4\frac{13}{24}+\frac{1}{8}-3\frac{1}{24}=1+\frac{13}{24}+\frac{3}{24}-\frac{1}{24}=1\frac{15}{24}=1\frac{5}{8}\).

б) \(3\frac{8}{9}+1\frac{3}{4}+\frac{1}{9}=4+1+\frac{8}{9}+\frac{1}{9}+\frac{3}{4}=6\frac{3}{4}\).

в) \(1+3\frac{5}{6}-7\frac{1}{6}-2\frac{2}{3}=4\frac{5}{6}-7\frac{1}{6}-2\frac{4}{6}=-5\).

г) \(4\frac{2}{3}+2\frac{3}{4}-1\frac{5}{12}=4\frac{8}{12}+2\frac{9}{12}-1\frac{5}{12}=6\).

Ответ: а) \(1\frac{5}{8}\); б) \(6\frac{3}{4}\); в) \(-5\); г) \(6\).
