A survey of 500 middle school students found that 420 of them spend more than 10 hours per week online.

Question

What percentage of middle schoolers spend more than 10 hours per week online? Show your work.

Answer 1

To find the percentage of middle school students who spend more than 10 hours per week online, we can use the following formula:

\[ \text{Percentage} = \left( \frac{\text{Number of students spending more than 10 hours online}}{\text{Total number of students}} \right) \times 100 \]

In this case:

• Number of students spending more than 10 hours online = 420
• Total number of students = 500

Now, we can substitute these values into the formula:

\[ \text{Percentage} = \left( \frac{420}{500} \right) \times 100 \]

Calculating \( \frac{420}{500} \):

\[ \frac{420}{500} = 0.84 \]

Now, we multiply by 100 to convert it into a percentage:

\[ 0.84 \times 100 = 84 \]

Thus, the percentage of middle schoolers who spend more than 10 hours per week online is \( \boxed{84%} \).
