The ratio of boys to girls in a school choir is 4:3. There are 6 more boys than girls. If another 2 girls join the choir, what will be the new ratio of boys to girls????

  • math -

    Ratio = Boys : Girls = 4 : 3

    4x = number of boys
    3x = number of girls

    4x - 6 = 3x
    x = 6

    4x = number of boys = 4 * 6 = 24
    3x = number of girls = 3 * 6 = 18

    If another 2 girls join the choir,
    18 + 2 = 20 = new number of girls
    24 = number of boys

    New ratio = 24 : 20 = 6 : 5
