$\frac{2}{x} = \frac{6}{7} \\ x = \frac{2 \times 7}{6} \\ x = \frac{1 \times 7}{3} \\ x = 2 \frac{1}{3}$

$\frac{3x}{1} = \frac{3}{8} \\ 3x = \frac{3}{8} \\ x = \frac{3}{8} \div 3 \\ x = \frac{3}{8 \times 3} \\ x = \frac{1}{8 \times 1} \\ x = \frac{1}{8}$

$\frac{0.2}{9} = \frac{x}{3} \\ x = \frac{0.2 \times 3}{9} \\ x = \frac{2 \times 3}{10 \times 9} \\ x = \frac{1 \times 1}{5 \times 3} \\ x = \frac{1}{15}$

$\frac{a}{3} = \frac{9}{x} \\ x = \frac{3 \times 9}{a} \\ x = \frac{27}{a}$
