Answer
$\frac{3}{10}$
Work Step by Step
First, we rewrite the given ratio as a fraction: $\frac{1.5x}{5x}$
Next, we find a common factor that is in both the numerator and the denominator, and factor it out: $\frac{0.5x(3)}{(0.5x)(10)}$
When you divide any number by itself, you get $1$, so we can cancel out the common factor. This leaves us with $\frac{3}{10}$.
