    Answer:

    Step-by-step explanation:

    boy count is 1476

    Explanation:

    There is an important difference between the way counts are viewed in ratio to that in fractions.

    The ratio of boys : girls

    4

    :

    5

    so you have 4 boys and 5 girls making the whole count

    4

    +

    5

    =

    9

    in its simplest form.

    So to change the ratio proportion into fraction proportion we have:

    boys

    4

    9

    of the whole.

    girls

    5

    9

    of the whole.

    It is given that the whole is 3321 therefore the count of boys is:

    4

    9

    ×

    3321

    =

    1476
