Solution:
we are given that
In a certain grocery store, strawberries cost $6.40 per pound ( 6.40 dollars/lb ).
we have been asked to find the cost per ounce?
As we know that
16 oz=1 lb
so we will divide by 16 to get the cost per ounce.
strawberries cost $6.40 per pound so for 1 oz it will cost 
$
Hence cost per ounce is 0.40 $
No because you would not be able to divide them by a number and get the same answer so no they are not proportional
