(a) Two different unit rates that can be determined are:
- 1 blueberry to 4 strawberries
- 3/12 blueberries to 12 strawberries (or 1/4 blueberries to 4 strawberries)
(b) To find out how many blueberries are needed if 16 strawberries are used, we can set up a proportion:
3 blueberries / 12 strawberries = x blueberries / 16 strawberries
Cross-multiplying, we get:
12x = 3 * 16
12x = 48
Dividing both sides by 12, we find:
x = 48 / 12
x = 4
Therefore, 4 blueberries are needed if 16 strawberries are used.
