In a class composed of x girls and y boys what part of the class is composed of girls ?

Options

A. `y/(x+y)`
B. `(x)/(xy)`
C. `(x)/((x+y))`
D. `(y)/(xy)`

Explanation

To find the part of the class that is composed of girls, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number of girls and boys**:
- Let the number of girls in the class be represented by \( x \).
- Let the number of boys in the class be represented by \( y \).

2. **Calculate the total number of students in the class**:
- The total number of students in the class is the sum of girls and boys, which can be expressed as:
\[ \text{Total students} = x + y \]

3. **Determine the part of the class that is composed of girls**:
- To find the part (or fraction) of the class that is composed of girls, we take the number of girls and divide it by the total number of students:
\[ \text{Part of girls} = \frac{x}{x + y} \]

4. **Conclusion**:
- The fraction of the class that is composed of girls is given by:
\[ \frac{x}{x + y} \]

### Final Answer:
The part of the class that is composed of girls is \( \frac{x}{x + y} \).
