    50:50 = 1:1 and 50 + 50 =100

    66:33 = 2:1 and 66 2/3 + 33 1/3 = 100 (close enough)

    75:25 = 3:1 and 75 + 25 = 100

    80:20 = 4:1 and 80 = 20 = 100

    84:16 = 5:1 (close enough) and 84 + 16 = 100

    The first number is the fraction times 100. The second number is 100 minus the first number.
