    So percent means parts out of 100

    so x%=x/100

    22 out of 105 have green eyes

    22/105

    we want to find an equivilent fraction that has 100 in the bottom that is equal so 22/105

    22/105=x/100

    solve for x

    multiply both sides by 100 to clear fraction

    2200/105=x

    simplify

    20.95=x

    round up

    21

    answe ris 21%
