Idon't understand what i'm supposed to do here. i have a test on this tomorrow so if you explain how to do it that would be great.

Here is a little tip for this: The unit above cancels the unit below. So in this problem you are asked to convert pounds to ounce. So your equation will look like this. 

ounce = 2.93 pounds 
Your ratio should involve the conversion factor. So 16 and 1 is involved canceling A and D. Then, Notice that you started with poubls. Then the ratio must have pounds at the bottom to cancel the units leaving ounces.
