40% of the students are girls.
Solution
To determine the percentage of girls in the class, you can use the following steps:
1. **Identify the numbers:**
- **Number of girls:** 12
- **Total number of students:** 30
2. **Use the percentage formula:**
\[
\text{Percentage of girls} = \left( \frac{\text{Number of girls}}{\text{Total number of students}} \right) \times 100
\]
3. **Plug in the numbers:**
\[
\text{Percentage of girls} = \left( \frac{12}{30} \right) \times 100
\]
4. **Calculate the division:**
\[
\frac{12}{30} = 0.4
\]
5. **Multiply by 100 to get the percentage:**
\[
0.4 \times 100 = 40\%
\]
**Conclusion:**
40% of the students in the class are girls.

Simplify this solution The Deep Dive
To find the percentage of girls in the class, you take the number of girls (12) and divide it by the total number of students (30), then multiply by 100. So, (12/30) * 100 = 40%. That means 40% of the students are girls—pretty empowering, right? In terms of numbers, percentages help us make sense of large quantities in a bite-sized way. For example, if you think of a pizza divided into 100 slices, a 40% portion means you’re getting 40 slices of deliciousness—definitely a generous serving!
