Explanation:

Step1: Find total number of 8th - graders

Add the number of 8th - graders who spend more and less than an hour on social media. $23 + 12=35$.

Step2: Calculate the percentage of 8th - graders who spend more than an hour

Use the formula $\text{Percentage}=\frac{\text{Number of 8th - graders who spend more}}{\text{Total number of 8th - graders}}\times100\%$. Substitute the values: $\frac{23}{35}\times100\%$.
$\frac{23}{35}\times100\%=\frac{2300}{35}\approx65.7\%$

Answer:

$65.7$
