Which container offers the best value? First, write each container as a ratio and then divide each ratio by its denominator to find the unit rate or unit price Finding unit prices

Next, divide each ratio by its denominator to find the price of one ounce (1.99/32) (3.99/64) (5.85/96) Now compare the prices for one ounce and determine which price is the best value
