What is ratio ?

Ratio is the comparison of two numbers i.e. how much a number contains other.

We have,

Number of girls $=24$

Ratio of girls to boys $=\ 3:8$

So,

According to the question,

Let number of girls $=3x$

Number of boys $=8x$

And,

We have number of girls so compare them,

i.e. $3x=24$

⇒$x= 8$

So, now putting value of $x$ in Number of boys,

i.e.

Number of boys $=8x$

                           $=8*8$

Number of boys $=64$

Hence, we can say that the number of boys will be $64$ .
