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
