Answer 1

Ответ:

$12 - 7 \frac{1}{6} = 11 \frac{6}{6} - 7 \frac{1}{6} = 4 \frac{6 - 1}{6} = 4 \frac{5}{6}$

$\frac{71}{4} - 3 \frac{7}{15} = 17 \frac{3}{4} - 3 \frac{7}{15} = 17 \frac{3 \times 15}{60} - 3 \frac{7 \times 4}{60} = 17 \frac{45}{60} - 3 \frac{28}{60} = 14 \frac{17}{60}$

$\frac{95}{12} - 6 \frac{2}{7} = 7 \frac{11}{12} - 6 \frac{2}{7} = 7 \frac{11 \times 7}{84} - 6 \frac{2 \times 12}{84} = 1 \frac{77 - 24}{84} = 1 \frac{53}{84 }$

$4 \frac{1}{6} - 2 \frac{4}{21} = 4 \frac{1 \times 7}{42} - 2 \frac{4 \times 2}{42} = 2 \frac{7 - 8}{42} = 2 - \frac{1}{42} = 1 \frac{42 - 1}{42} = 1 \frac{41}{42 }$
