    Number of boys competing = 25

    Step-by-step explanation:

    The ratio of girls to boys competing at a gymnastics competition was 2:1

    Number of girls competing : Number of boys competing = 2 : 1

    There was 75 kids participating in the competition

    Total number of participants = 75

    Number of girls competing + Number of boys competing = 2x + x = 3x

    Total number of participants = 75 = 3x

    3 x = 75

    x = 25

    Number of boys competing = x = 25

    Number of boys competing = 25
