Ratio of the number of students on the team to the number of students trying out for girls is given by
[tex] \frac{12}{30} = \frac{2}{5} [/tex]
Ratio of the number of students on the team to the number of students trying out for boys is given by
[tex] \frac{16}{40} = \frac{2}{5} [/tex]
Since both ratios, simplify to [tex]\frac{2}{5}[/tex], thus the ratios of the number of students on the team to the number of students trying out is the same for both boys and girls.
