Question

There are 3/4 as many boys as girls in a class of fifth-graders. If there are 35 students in the class, how many are girls?

Answer 1

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!
