Answer:

#12# boys

Explanation:

We know that there is a ratio of #3:2# of girls:boys

We know that there are #18# girls so we can see that the #3# in the ratio refers to #18# people.

Know that we know that #3# means #18# people, we can figure out that #1# would mean #6# people.

As there are #2# boys in the ratio, there are #6xx2# boys in the class.
