Known Facts:

  • 3/4 as many boys as girls in a class
  • Five students in the class

Variables:

  • b: boys
  • g: girls

Let us set up some equations:

  • b + g = 35
  • b = (3/4)g

Now let us solve the equation:

   b + g =35

   (3/4)g + g = 35

    (7/4)g = 35

     g = 20

Therefore there are 20 girls in a class of 35!

Good day and I hope that helped!
