Answer:
Step-by-step explanation:
1. **Find the number of boys:**
- You need to calculate \(\frac{3}{5}\) of 90.
\[
\text{Number of boys} = \frac{3}{5} \times 90
\]
\[
\text{Number of boys} = \frac{3 \times 90}{5}
\]
\[
\text{Number of boys} = \frac{270}{5}
\]
\[
\text{Number of boys} = 54
\]
### 2. Calculate the Number of Girls
2. **Find the number of girls:**
- Subtract the number of boys from the total number of children.
\[
\text{Number of girls} = 90 - \text{Number of boys}
\]
\[
\text{Number of girls} = 90 - 54
\]
\[
\text{Number of girls} = 36
\]
### Summary
- **Number of boys**: 54
- **Number of girls**: 36
