Answer 1

Assuming the table gives 5 pounds of rice with 2 liters of water, the mix is 5 lb rice per 2 L water.

- Unit rates: 5/2 = 2.5 lb rice per 1 L water (true), and 2/5 = 0.4 L water per 1 lb rice (true).

- Scaling: multiplying 5 lb and 2 L by 5 gives 25 lb and 10 L (true). Doubling 5 lb gives 10 lb and doubles 2 L to 4 L, not 25 L (false).

So A, B, and C are true; D is false.
