Calculate Total Students: Converting 240 Girls at 30% to Full Population

The number of female students participating in the 7th grade camp is 240, and their percentage is 30% of all students participating in the camp. Find the number of students (including girls and boys) participating in the summer camp.

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information
• Step 2: Convert the percentage to a decimal
• Step 3: Use the percentage formula
• Step 4: Calculate the total number of students

Now, let's work through each step:
Step 1: The problem gives us the number of female students participating in the camp, which is 240.
Step 2: Convert the percentage of females into a decimal: $30\% = \frac{30}{100} = 0.30$.
Step 3: Apply the formula for total students:
$\text{Total number of students} = \frac{240}{0.30}$
Step 4: Perform the calculation:
$\frac{240}{0.30} = 800$
Thus, the total number of students participating in the summer camp is 800.

Therefore, the solution to the problem is 800.
