  1. green : yellow = 2:5
    yellow : orange = 3:4
    green : orange = 3:10

    if 30 green
    then 75 yellow
    and 100 orange

    30:100 = 3:10

  2. Or

    green : yellow = 2:5
    yellow : orange = 3:4
    green : orange = 3:10

    if 2 green
    then 5 yellow
    and 20/3 orange

    2 : 20/3 = 3:10
