If 3 half-gallon containers of ice cream on sale for $6.69,what is the price for 2 half-gallon containers?

Work Shown:

3 containers = 6.69 dollars

3/3 containers = 6.69/3 dollars divide both sides by 3

1 container = 2.23 dollars

2*(1 container) = 2*(2.23 dollars) ... multiply both sides by 2

2 containers = 4.46 dollars

A shortcut is to start with "3 containers = 6.69 dollars" and multiply both sides by 2/3

Each mention of "container" refers to a half-gallon container.
