The ratio of oil to vinegar is 2:1.
To determine which of the given ratios are equivalent, we need to simplify each ratio:
A) 18:6 -> Simplifying, we get 3:1, which is not equivalent to 2:1.
B) 30:15 -> Simplifying, we get 2:1, which is equivalent to 2:1.
C) 8:4 -> Simplifying, we get 2:1, which is equivalent to 2:1.
D) 21:4 -> Simplifying, we get 5.25:1, which is not equivalent to 2:1.
E) 20:10 -> Simplifying, we get 2:1, which is equivalent to 2:1.
The ratios that are equivalent to the ratio of oil to vinegar are B) 30:15 and E) 20:10.
Therefore, the answer is (B) and (E).
