You can put this solution on YOUR website!
First set up an equation
3%2F4=240
Then in order to find out the total amount of students, we need a variable. Plug it next to the fraction.
3%2F4x=240
Then get rid of the 3%2F4 by multiplying it by its recipricol (flip the fraction upside-down)
You should get X=240%2A%284%2F3%29
Then solve.
X=320
