I won't give the answer, but here's the process: You have the weight of the object (0.500 lbs), and you want to convert that into the number of kernels. You are given the fact that 1 pound = 16 oz, and 1 oz=28.3 grams. So it should be apparent that you need to convert pounds to ounces first and then convert ounces to grams. Now that you the grams, you can easily figure out how many kernels there are because .125 grams equals the weight of one kernel.
