Mathematics

Step-by-step explanation:

Let total number of girls and boys be x and y respectively.

$\therefore \: \frac{3}{4} x = \frac{2}{5} y \\ \\ \therefore \: \frac{x}{y} = \frac{2}{5} \times \frac{4}{3} \\ \\ \therefore \: \frac{x}{y} = \frac{2 \times 4}{5 \times 3} \\ \\ \therefore \: \frac{x}{y} = \frac{8}{15} \\ \\$
