The two different unit rates for assembling boxes of fudge in a candy shop that uses a ratio of 27 pieces of dark chocolate to 9 pieces of milk chocolate are 3 pieces of dark chocolate per 1 piece of milk chocolate and 3 pieces of dark chocolate per 1 piece of milk chocolate.
Step-by-step explanation:
The ratio of 27 pieces of dark chocolate to 9 pieces of milk chocolate can be simplified to 3 pieces of dark chocolate to 1 piece of milk chocolate. This means that for every 3 pieces of dark chocolate, there is 1 piece of milk chocolate.
