From the present question, it was given the number of girls and boys from a class. It is 16 and 6, respectively.
The ratio of boys and girls is given by:
[tex]R=\frac{N\degree_{\text{boys}}}{N\degree_{\text{girls}}}=\frac{6}{16}[/tex]We can perform the calculation as follows:
[tex]R=0.375[/tex]From the present solution, we conclude that the ratio of boys to girls in the class is 0.375
