(a) Two different unit rates using this relationship can be:
1) 27 pieces of dark chocolate : 9 pieces of milk chocolate
Simplifying the ratio by dividing both parts by 27, we get:
1 piece of dark chocolate : 1/3 piece of milk chocolate
2) Alternatively, we can multiply the ratio by 3 to get:
27 pieces of dark chocolate : 9 pieces of milk chocolate
= 81 pieces of dark chocolate : 27 pieces of milk chocolate
(b) If 30 pieces of dark chocolate are used, we can find the number of pieces of milk chocolate needed by using the ratio.
Given ratio: 27 pieces of dark chocolate : 9 pieces of milk chocolate
Since the ratio is equal, we can set up a proportion.
27 pieces of dark chocolate / 9 pieces of milk chocolate = 30 pieces of dark chocolate / x pieces of milk chocolate
Simplifying the proportion, we get:
3 pieces of dark chocolate / 1 piece of milk chocolate = 10 pieces of dark chocolate / x pieces of milk chocolate
To solve for x, we can cross multiply:
3x = 10
x = 10/3
Therefore, 10/3 pieces of milk chocolate are needed if 30 pieces of dark chocolate are used.

I apologize for the error. Let me correct myself.
(a) Two different unit rates using this relationship can be:
1) 27 pieces of dark chocolate : 9 pieces of milk chocolate
To find the unit rate, we can simplify the ratio by dividing both parts by the greatest common divisor, which is 9.
27/9 = 3 pieces of dark chocolate : 1 piece of milk chocolate
2) Alternatively, we can multiply the ratio by 3 to get:
27 pieces of dark chocolate : 9 pieces of milk chocolate
81 pieces of dark chocolate : 27 pieces of milk chocolate
(b) If 30 pieces of dark chocolate are used, we can use the unit rate from previous part (1) to find the number of pieces of milk chocolate needed.
3 pieces of dark chocolate : 1 piece of milk chocolate
Since the unit rate is 3 pieces of dark chocolate to 1 piece of milk chocolate, we can set up a proportion:
3 pieces of dark chocolate / 1 piece of milk chocolate = 30 pieces of dark chocolate / x pieces of milk chocolate
To solve for x, we can cross multiply:
3x = 30
x = 30/3
x = 10
Therefore, 10 pieces of milk chocolate are needed if 30 pieces of dark chocolate are used.
