Answer:
Step-by-step explanation:
This is basically just a ratio. If the ratio between the amount of girls to the amount of boys is 8 to 6, then we can create a fraction (girls/boys)
Using what we know about the second statement (24 girls) we can make a ratio like this (also assuming girls/boys)
Since the ratios must be equal, we can set them equal to each other.
We can cross multiply to find x.
So there are 18 boys.
