#### Answer:

There are $16$ boys.

#### Explanation:

Since there are $12$ girls, we can divide $12$ by the given ratio, $3$

$\frac{12}{3} = 4$

So we know that the factor we are multiplying is $4$. Using the $3 : 4$ ratio, $3$ representing girls and $4$ representing boys, you can multiply $4$ by $4$

$4 \cdot 4 = 16$
