There are 'b' boys and 'g' girls in a class. The ratio of the number of boys to the total number of students in the class is:

Options

A. `(b)/( b + g)`
B. `(g)/(b + g)`
C. `(b)/(g)`
D. `(b + g)/(b)`

Answer

To find the ratio of the number of boys to the total number of students in a class where there are 'b' boys and 'g' girls, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number of boys and girls**:
- The number of boys in the class is given as \( b \).
- The number of girls in the class is given as \( g \).

2. **Calculate the total number of students**:
- The total number of students in the class is the sum of boys and girls.
- Therefore, the total number of students is \( b + g \).

3. **Set up the ratio**:
- The ratio of the number of boys to the total number of students can be expressed as:
\[ \text{Ratio} = \frac{\text{Number of Boys}}{\text{Total Number of Students}} = \frac{b}{b + g} \]

4. **Final expression**:
- Thus, the ratio of the number of boys to the total number of students is:
\[ \frac{b}{b + g} \]

### Conclusion:
The ratio of the number of boys to the total number of students in the class is \( \frac{b}{b + g} \).
