6 boys, 15 girls

Step-by-step explanation:

I will use B for boys and G for girls

$\frac{B}{G} = \frac{2}{5} \\G = B + 9\\\frac{B}{B+9} =\frac{2}{5}\\$

Cross multiply

$5B = 2(B + 9)\\5B = 2B + 18\\3B = 18\\B = 6$

There are 6 boys, so that means that there are 15 girls

A ratio of 6:15 can be simplified by dividing by 3

6/3:15/3 = 2:5
