Answer
$x = 0.02$
$x = \frac{2}{100}$
Work Step by Step
$\frac{0.15}{0.1} = \frac{0.03}{x}$
$0.15x = (0.1)(0.03)$
$0.15x = 0.003$
$\frac{0.15x}{0.15} = \frac{0.003}{0.15}$
$x = 0.02$
$\frac{\frac{3}{20}}{\frac{1}{10}} = \frac{\frac{3}{100}}{x}$
$\frac{3x}{20} = (\frac{1}{10})(\frac{3}{100})$
$(\frac{3x}{20})(\frac{20}{3}) = (\frac{3}{1000})(\frac{20}{3})$
$x = \frac{20}{1000}$
$x = \frac{2}{100}$
