Ответ:

$\frac{3}{28} \div \frac{6}{7} = \frac{3}{28} \times \frac{7}{6} = \frac{3 \times 7}{28 \times 6} = \frac{21}{168} = \frac{1 \times 21}{8 \times 21} = \frac{1}{8}$

$\frac{3}{8} \div \frac{27}{32} = \frac{3}{8} \times \frac{23}{27} = \frac{3 \times 32}{8 \times 27} = \frac{96}{216} = \frac{4 \times 24}{9 \times 24} = \frac{4}{9}$

$\frac{5}{6} \div 10 = \frac{5}{6 \times 10} = \frac{5}{60} = \frac{1 \times 5}{12 \times 5} = \frac{1}{12}$

$\frac{3}{7} \div 12 = \frac{3}{7 \times 12} = \frac{3}{84} = \frac{1 \times 3}{28 \times 3} = \frac{1}{28}$

$25 \div \frac{5}{8} = 25 \times \frac{8}{5} = \frac{25 \times 8}{5} = \frac{200}{5} = \frac{40 \times 5}{5} = 40$

$8 \div \frac{16}{21} = 8 \times \frac{21}{16} = \frac{8 \times 21}{16} = \frac{168}{16} = \frac{21 \times 8}{2 \times 8} = \frac{21}{2} = \frac{10 \times 2 + 1}{2} = 10 \frac{1}{2}$

$\frac{2}{5} \div 7 = \frac{2}{5 \times 7} = \frac{2}{35}$

$\frac{3}{4} \div \frac{9}{16} = \frac{3}{4} \times \frac{16}{9} = \frac{3 \times 16}{4 \times 9} = \frac{48}{36} = \frac{4 \times 12}{3 \times 12} = \frac{4}{3} = \frac{1 \times 3 + 1}{3} = 1 \frac{1}{3}$
