Question

In 6th grade,there are 5 boys for every 4 girls. If there are 198 6th graders, how many boys are there?

2 Answer

  • 5:4
    5+4=9 
    198/9=22
    22*5=
    110:88
    there are 110 boys
  • We are given 5 boys for every four girls. We could set up an equation and solve for x.

    5x+4x=198
    9x=198
    x=22
    now plug in x = 22 back for 5x to find the total number of boys
    5(22) =110  boys
    we could also let x = 22 for 4x to find the total number of girls (even though we're not asked to do this)
    4(22) = 88 girls
