Answer

Explanation:

Step1: Simplify the fraction

We have the fraction $\frac{9}{30}$. Divide both numerator and denominator by 3. $\frac{9\div3}{30\div3}=\frac{3}{10}$

Step2: Convert to decimal

To convert $\frac{3}{10}$ to a decimal, we know that $\frac{3}{10}=3\div10$. $3\div10 = 0.3$

Answer:

$0.3$
