Given:

In a computer lab, there are 3 computers for every 6 students.

To find:

How many computers will be needed for 24 students

Solution:

According to the question,

Every 6 students require = 3 computers in the computer lab

So, using the unitary method, we get

1 computer will be used by = $\frac{6}{3}$ = 2 students

Therefore,

24 computers will be used by,

= $\frac{No. \:of\: computers}{No. \:of\: students\: using \:1\: computer}$

= $\frac{24}{2}$

= $\bold{12}$
