Answer
$x = 0.005$
$x = \frac{5}{1000}$
Work Step by Step
$\frac{x}{0.06} = \frac{0.15}{1.8}$
$1.8x = (0.15)(0.06)$
$1.8x = 0.009$
$\frac{1.8x}{1.8} = \frac{0.009}{1.8}$
$x = 0.005$
$\frac{x}{\frac{3}{50}} = \frac{\frac{15}{100}}{1\frac{4}{5}}$
$1\frac{4}{5}x = (\frac{3}{50})(\frac{15}{100})$
$\frac{9}{5}x = \frac{45}{5000}$
$\frac{9}{5}x(\frac{5}{9}) = (\frac{45}{5000})(\frac{5}{9})$
$\frac{9}{5}x(\frac{5}{9}) = (\frac{45\div9}{5000\div5})(\frac{5\div5}{9\div9})$
$x = \frac{5}{1000}$
