Ответ:
- 50. 1) \( 14\frac{1}{4} + 7\frac{5}{6} = 14\frac{3}{12} + 7\frac{10}{12} = 21\frac{13}{12} = 22\frac{1}{12} \)
- 50. 2) \( 4\frac{11}{18} + 8\frac{7}{12} = 4\frac{22}{36} + 8\frac{21}{36} = 12\frac{43}{36} = 13\frac{7}{36} \)
- 50. 3) \( 7\frac{5}{24} + 2\frac{3}{16} = 7\frac{10}{48} + 2\frac{9}{48} = 9\frac{19}{48} \)
- 50. 4) \( 7\frac{5}{16} + 4\frac{1}{6} + 3\frac{3}{8} = 7\frac{15}{48} + 4\frac{8}{48} + 3\frac{18}{48} = 14\frac{41}{48} \)
- 51. 1) \( 8\frac{7}{8} - 5\frac{3}{4} = 8\frac{7}{8} - 5\frac{6}{8} = 3\frac{1}{8} \)
- 51. 2) \( 7\frac{7}{15} - 4\frac{5}{18} = 7\frac{42}{90} - 4\frac{25}{90} = 3\frac{17}{90} \)
- 51. 3) \( 16\frac{11}{18} - 8\frac{8}{27} = 16\frac{33}{54} - 8\frac{16}{54} = 8\frac{17}{54} \)
- 51. 4) \( 8\frac{17}{28} - 7\frac{23}{42} = 8\frac{51}{84} - 7\frac{46}{84} = 1\frac{5}{84} \)
- 52. 1) \( 6\frac{1}{14} - 1\frac{1}{7} = 6\frac{1}{14} - 1\frac{2}{14} = 5\frac{15}{14} - 1\frac{2}{14} = 5\frac{13}{14} \)
- 52. 2) \( 8\frac{9}{40} - 6\frac{13}{50} = 8\frac{45}{200} - 6\frac{52}{200} = 7\frac{245}{200} - 6\frac{52}{200} = 1\frac{193}{200} \)
- 52. 3) \( 5\frac{5}{6} - 2\frac{6}{7} = 5\frac{35}{42} - 2\frac{36}{42} = 4\frac{77}{42} - 2\frac{36}{42} = 2\frac{41}{42} \)
- 52. 4) \( 9\frac{7}{34} - 1\frac{29}{102} = 9\frac{21}{102} - 1\frac{29}{102} = 8\frac{123}{102} - 1\frac{29}{102} = 8\frac{94}{102} = 8\frac{47}{51} \)
- 52. 5) \( 8\frac{3}{8} - 5\frac{5}{6} = 8\frac{9}{24} - 5\frac{20}{24} = 7\frac{33}{24} - 5\frac{20}{24} = 2\frac{13}{24} \)
- 52. 6) \( 7\frac{13}{36} - 3\frac{25}{54} = 7\frac{39}{108} - 3\frac{50}{108} = 6\frac{147}{108} - 3\frac{50}{108} = 3\frac{97}{108} \)
