Answer

Explanation:

Step1: Identify relevant values

The number of 8th - graders who spend less than an hour on social - media is 25, and the total number of 8th - graders is 55.

Step2: Calculate the percentage

The formula for percentage is $\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100%$. Here, the part is 25 (8th - graders spending less than an hour) and the whole is 55 (total 8th - graders). So, $\text{Percentage}=\frac{25}{55}\times100%$. $\frac{25}{55}\times100%=\frac{2500}{55}% \approx 45.45%$.

Step3: Round to the nearest whole number

Rounding 45.45% to the nearest whole number gives 45%.

Answer:

45%
