Given that
There are 60 girls and the ratio of boys to girls is 6:5.
Explanation -
Let the boys be b.
Then the ratio can be represented in fraction form as
[tex]\begin{gathered} \frac{b}{g}=\frac{6}{5} \\ \frac{b}{60}=\frac{6}{5} \\ b=\frac{6}{5}\times60=6\times12=72 \\ So\text{ there are 72 boys.} \end{gathered}[/tex]Hence, the final answer is 72.
