Answer:
There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:
There might be 3 boys and 2 girls.
There might be 6 boys and 4 girls.
There might be 9 boys and 6 girls.
There might be 12 boys and 8 girls.
etc...
In each case the ratio stays the same - 3 : 2.
Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.
