the ratio of males to females in a college class is 2:6. if there are 72 students in the class, how many are males?
is it 36 males?

36 males is 1/2 the class.
But your problem states that the ratio is 2:6 or 1:3.
Please try again. 
ok I see, so then it would be 24 males

nope. If it is 24 males, then females should be 3x or 72. That wont work at all.
2:6 means 8 parts. Divide 72 by 8
2 parts are male
6 parts are notmale
