а) $$1 \frac{4}{17} - \frac{4}{17} = 1$$
б) $$6 \frac{6}{11} - 5 \frac{6}{11} = 1$$
в) $$5 \frac{7}{13} - \frac{7}{13} = 5$$
г) $$4 \frac{5}{9} - 3 = 1 \frac{5}{9}$$
д) $$4 \frac{9}{16} - 2 \frac{3}{14} = \frac{73}{16} - \frac{31}{14} = \frac{73 \cdot 7 - 31 \cdot 8}{112} = \frac{511 - 248}{112} = \frac{263}{112} = 2 \frac{39}{112}$$
e) $$11 \frac{7}{32} - 9 \frac{11}{64} = \frac{359}{32} - \frac{587}{64} = \frac{718 - 587}{64} = \frac{131}{64} = 2 \frac{3}{64}$$
ж) $$17 \frac{8}{15} - 6 \frac{7}{12} = \frac{263}{15} - \frac{79}{12} = \frac{263 \cdot 4 - 79 \cdot 5}{60} = \frac{1052 - 395}{60} = \frac{657}{60} = \frac{219}{20} = 10 \frac{19}{20}$$
з) $$24 \frac{7}{15} - 15 \frac{5}{12} = \frac{367}{15} - \frac{185}{12} = \frac{367 \cdot 4 - 185 \cdot 5}{60} = \frac{1468 - 925}{60} = \frac{543}{60} = \frac{181}{20} = 9 \frac{1}{20}$$
