    50% as a fraction is=1/2.

    1/2 of 7=3.

    1/2 is 3=7 (always divide by the bottom and times by the top).

    7+3=10.

    70+30 = 100.

    Half 100 is 50.

    So 30 or 3 is the number.

    50 percent of a number is 7

    Set up an equation.

    50% * x = 7

    0.50 * x = 7

    0.50x = 7

    Divide 0.50 to both sides:

    x = 14
