Answer 1

Ответ:

$6 - 5 \frac{5}{8 } = 5 \frac{8}{8} - 5 \frac{5}{8} = (5 - 5) + ( \frac{8 - 5}{8} ) = \frac{3}{8}$

$6 \frac{3}{10} - \frac{11}{15} = \frac{63}{10} - \frac{11}{15} = \frac{189 - 22}{30} = \frac{167}{30} = 5 \frac{17}{30}$

$7 \frac{4}{7} - 5 \frac{7}{9} = (6 - 5) + \frac{99 - 49}{63} = 1 \frac{50}{63}$

$8 \frac{3}{11} - 4 = (8 - 4) + \frac{3}{11} = 4 \frac{3}{11}$

$5 \frac{7}{8} - \frac{9}{10} = 4 + ( \frac{15}{8} - \frac{9}{10} ) = 4 + ( \frac{75 - 36}{40} ) = 4 \frac{39}{40}$

$2 \frac{3}{10} - 1 \frac{11}{15} = (1 - 1) + ( \frac{13}{10} - \frac{11}{15} ) = \frac{39 - 22}{30} = \frac{17}{30}$

$5 \frac{7}{15} - \frac{3}{20} = 5 + ( \frac{28 - 9}{60} ) = 5 \frac{19}{60}$

$7 \frac{5}{12} - 3 \frac{2}{9} = (7 - 3) + ( \frac{15 - 8}{36} ) = 4 \frac{7}{36}$

$5 \frac{3}{8} - 3 \frac{5}{6} = (4 - 3) + ( \frac{11}{8} - \frac{5}{6} ) = 1 + ( \frac{33 - 20}{24} ) = 1 \frac{13}{24}$
