Answer 1

Ответ:

$1) \: \: \: 3 \frac{4}{5} - 2 \frac{3}{5} = 1 \frac{1}{5} \\ 2) \: \: \: 7 \frac{5}{6} - 4 \frac{2}{3} = 3 \frac{5 - 2 \times 2}{6} = 3 \frac{1}{6} \\ 3) \: \: \: 4 \frac{5}{6} - 2 \frac{5}{12} = 2 \frac{5 \times 2 - 5}{12} = 2 \frac{5}{12} \\ 4) \: \: \: 10 \frac{4}{9} - 8 \frac{5}{18} = 2 \frac{4 \times 2 - 5}{18} = 2 \frac{3}{18} = 2 \frac{1}{6} \\ 5) \: \: \: 9 \frac{1}{2} - 2 \frac{1}{4} = 7 \frac{1 \times 2 - 1}{4} = 7 \frac{1}{4} \\ 6) \: \: \: 6 \frac{3}{4} - 2 \frac{2}{3} = 4 \frac{3 \times 3 - 2 \times 4}{12} = 4 \frac{9 - 8}{12} = 4 \frac{1}{12}$

$7) \: \: \: 11 \frac{3}{7} - 5 \frac{1}{3} = 6 \frac{3 \times 3 - 7}{21} = 6 \frac{2}{21} \\ 8) \: \: \: 8 \frac{3}{5} - 6 \frac{3}{10} = 2 \frac{3 \times 2 - 3}{10} = 2 \frac{3}{10}$
