Answer

Explanation:

Step1: Substitute values

Substitute $x = 45$ and $s = 9$ into the $CV$ formula $CV=\frac{s}{x}\times100%$. So we get $CV=\frac{9}{45}\times100%$.

Step2: Simplify fraction

Simplify $\frac{9}{45}$ to $\frac{1}{5}$. Then $CV=\frac{1}{5}\times100%$.

Step3: Calculate percentage

$\frac{1}{5}\times100% = 20%$.

Answer:

$20%$
