Question

in math class, the girl to boy i 8 to 6. if there are 24 girl in the class, how many boy are there?

Answer 1

Answer:

$\huge\boxed{\text{18 boys}}$

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)

$\frac{8}{6}$

Using what we know about the second statement (24 girls) we can make a ratio like this (also assuming girls/boys)

$\frac{24}{x}$

Since the ratios must be equal, we can set them equal to each other.

$\frac{8}{6} = \frac{24}{x}$

We can cross multiply to find x.

$24 \cdot 6 = 144\\\\144 \div 8 = 18$

So there are 18 boys.

Hope this helped!
