She has 80 students in her classes.

3/4 of 80 = 60.

First off let's start with 1/4 of 80.

80/4 = 20.

But the question asks for 3/4 and that’s three times more than 1/4 so you multiply 3 to 20.

20*3 = 60.

So your answer is 60.

So there are a couple ways to do this. You should figure out what 3/4 of 80 is. This could also be written as 3:4 = x:80. 80/4= 20. x/3= 20 as 3*20= 60. X=60, therefor 60 students prefer cheese. To check, see if 60/80 : 3/4. 60/3= 20 and 80/4 = 20
