Answer:
27 girls and 15 boys
Step-by-step explanation:
To solve this, I just used guess and check.
9:5 is a ratio, which means we can multiply each side by any number as long as we do it to both sides.
If we multiply the ratio by 3, we get (9 x 3) : (5 x 3) which is 27:15
And as it turns out, 27-15 is 12, which in this context means there are 12 more girls in drama club, so it works out.
Answer:
