In a class of 20 students, 5 are boys and remaining are girls. Find the percentage of girls.

Explanation

To find the percentage of girls in the class, we can follow these steps:

### Step 1: Determine the number of girls in the class.
- Total students = 20
- Number of boys = 5
- Number of girls = Total students - Number of boys
- Number of girls = 20 - 5 = 15

### Step 2: Use the percentage formula.
The formula to calculate the percentage is:
\[ \text{Percentage} = \left( \frac{\text{Number of girls}}{\text{Total students}} \right) \times 100 \]

### Step 3: Substitute the values into the formula.
- Number of girls = 15
- Total students = 20
\[ \text{Percentage of girls} = \left( \frac{15}{20} \right) \times 100 \]

### Step 4: Calculate the fraction.
\[ \frac{15}{20} = 0.75 \]

### Step 5: Multiply by 100 to get the percentage.
\[ 0.75 \times 100 = 75 \]

### Final Answer:
The percentage of girls in the class is **75%**.
