• а) \(5\frac{7}{15}-\frac{3}{20}=5+\frac{28-9}{60}=5\frac{19}{60}\);
• б) \(4\frac{7}{12}-\frac{2}{9}=4+\frac{21-8}{36}=4\frac{13}{36}\);
• в) \(6\frac{5}{7}-\frac{3}{14}=6+\frac{10-3}{14}=6\frac{1}{2}\);
• г) \(7\frac{5}{7}-4\frac{2}{3}=3+\frac{15-14}{21}=3\frac{1}{21}\);
• д) \(3\frac{2}{3}-3\frac{4}{11}=\frac{22-12}{33}=\frac{10}{33}\);
• е) \(7\frac{5}{12}-3\frac{2}{9}=4+\frac{15-8}{36}=4\frac{7}{36}\).
