franklin school has 3 boys for every four girls in the fifth grade. there are 140 students in the fifth grade. many are boys? many are girls?

  • math -

    Add the ratio
    So each part of the ratio is worth 7.
    so then divide 140 by 7 = 20
    Now we know there were 3 boys for every 4 girls
    So the amount of boys in the school = 20 multiply by 3 = 60
    The amount of girls in the school= 20 multiply by 4 = 80
    So add 80 + 60= 140 so you got back what you started with
