Решите задачу:

$\frac{18}{25} \div \frac{3}{5} = \frac{18 \times 5}{25 \times 3} = \frac{6}{5} = 1 \frac{1}{5} \\ 2 \frac{5}{8} \div 2 \frac{1}{4} = \frac{21 \times 4}{8 \times 9} = \frac{7}{6} = 1 \frac{1}{6} \\ 7 \div \frac{14}{15} = \frac{7 \times 15}{14} = \frac{15}{2} = 7 \frac{1}{2} \\ \frac{16}{17} \div 8 = \frac{16}{17 \times 8} = \frac{2}{17} \\ \\ 16 \div 4 \times 5 = 20 \: ves \: put \\ 54 \div 0.18 = 300 \: kg \: medi \\ (9 - 2 \frac{1}{7} \div \frac{9}{14} ) \div 2 \frac{4}{15} = \\ 1). \: \: 2 \frac{1}{7} \div \frac{9}{14} = \frac{15 \times 14}{7 \times 9} = \frac{10}{3} = 3 \frac{1}{3} \\ 2). \: \: 9 - 3 \frac{1}{3} = 8 \frac{3}{3} - 3 \frac{1}{3} = 5 \frac{2}{3} \\ 3). \: \: 5 \frac{2}{3} \div 2 \frac{4}{15} = \frac{17 \times 15}{3 \times 34} = \frac{5}{2} = 2 \frac{1}{2} \\ \\ \frac{2}{3} = 0.6(6)$
