    Trail mix weight: 2 lb

    Oats : 20 %

    a) Equation

    Weight of oat = 2 lb * 20% * 2 lb = 2 lb * 20 / 100

    You must know that part / whole = percent / 100

    20 / 100 = (x) / 2

    20 is the percent x is the part and 2 is the whole

    b) Result

    Weight of oat = x = (20/100) * 2lb = 0.4 lb
