To determine the ratio of boys to girls in the choir, we need to compare the number of boys to the number of girls.
Given:
- There are 4 boys.
- There are 5 girls.
The ratio of boys to girls is calculated by dividing the number of boys by the number of girls.
The ratio of boys to girls = [tex]\(\frac{\text{number of boys}}{\text{number of girls}}\)[/tex] = [tex]\(\frac{4}{5}\)[/tex].
Hence, the correct answer is:
A. [tex]\(\frac{4}{5}\)[/tex].
