A bag of trail mix weighs 2 lb. By weight, 20% of the bag is oats. (a) Write an equation for the situation and label the "part," "whole," and "percent." (b) What is the weight of the oats in the trail mix? Show your work!

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
