In a school election 3/4 of the students vote. there are 1464 ballots. write and solve an equation to find the number of students

A simple way to turn this into an equation is by replacing the words with letters: 
1464B = 3/4 S

Then you have to remove the 3/4 from the right side of the equation.  You can do this by dividing both sides by 3/4: 
1464 / 3/4 = S

Then you have to do the sum: 
   1464 
 / 3
= 0488

     488 
     X  4
= 1952

There are 1952 students.
