For every 6 apple pie, you need 2 pounds of apples. So, how many pounds of apples do you need for 10 apple pies? Well, first to figure out this question we first need to make a conversion factor. I see in the fraction 6/3 we can simplify that to 2/1. Now we got our conversion factor. We need to invert the fraction in order for the pie unit to cancel out. 1/2 * 10 = 5
You will need 5 pounds of apples to make 10 apple pies.
