Домашнее задание от 10.02.2025: 1 случай 2 случай 3 случай 4 случай 5 случай 6 случай 1) 1 - 4/9 2) 7 - 5/11 3) 4 - 3 3/5 4) 9 7/8 - 4 5) 8 15/18 - 1 7/12 6) 5 3/8 - 3 5/7 1) 1 - 3/8 2) 5 - 2/13 3) 8 - 2 5/7 4) 7 6/11 - 5 5) 9 2/15 - 5 1/12 6) 6 4/7 - 3 7/9

1. 1 случай:
   1. 1) \[ 1 - \frac{4}{9} = \frac{9}{9} - \frac{4}{9} = \frac{5}{9} \]
   2. 2) \[ 7 - \frac{5}{11} = \frac{77}{11} - \frac{5}{11} = \frac{72}{11} = 6\frac{6}{11} \]
   3. 3) \[ 4 - 3\frac{3}{5} = 4 - \frac{18}{5} = \frac{20}{5} - \frac{18}{5} = \frac{2}{5} \]
   4. 4) \[ 9\frac{7}{8} - 4 = \frac{79}{8} - \frac{32}{8} = \frac{47}{8} = 5\frac{7}{8} \]
   5. 5) \[ 8\frac{15}{18} - 1\frac{7}{12} = \frac{159}{18} - \frac{19}{12} = \frac{318}{36} - \frac{57}{36} = \frac{261}{36} = \frac{29}{4} = 7\frac{1}{4} \]
   6. 6) \[ 5\frac{3}{8} - 3\frac{5}{7} = \frac{43}{8} - \frac{26}{7} = \frac{301}{56} - \frac{208}{56} = \frac{93}{56} = 1\frac{37}{56} \]
2. 2 случай:
   1. 1) \[ 1 - \frac{3}{8} = \frac{8}{8} - \frac{3}{8} = \frac{5}{8} \]
   2. 2) \[ 5 - \frac{2}{13} = \frac{65}{13} - \frac{2}{13} = \frac{63}{13} = 4\frac{11}{13} \]
   3. 3) \[ 8 - 2\frac{5}{7} = 8 - \frac{19}{7} = \frac{56}{7} - \frac{19}{7} = \frac{37}{7} = 5\frac{2}{7} \]
   4. 4) \[ 7\frac{6}{11} - 5 = \frac{83}{11} - \frac{55}{11} = \frac{28}{11} = 2\frac{6}{11} \]
   5. 5) \[ 9\frac{2}{15} - 5\frac{1}{12} = \frac{137}{15} - \frac{61}{12} = \frac{548}{60} - \frac{305}{60} = \frac{243}{60} = \frac{81}{20} = 4\frac{1}{20} \]
   6. 6) \[ 6\frac{4}{7} - 3\frac{7}{9} = \frac{46}{7} - \frac{34}{9} = \frac{414}{63} - \frac{238}{63} = \frac{176}{63} = 2\frac{50}{63} \]
