Answer:
Yes
Step-by-step explanation:
A ratio (x:y) can also be written as a fraction (x/y). Fractions can then be divided to get the answer of what that ratio equals. If both of the ratios can be divided to equal the same number, they are equal.
3 cups of peanuts : 2 cups of raisins is equal to 1.5 (3/2 = 1.5)
4.5 cups of peanuts : 3 cups of raisins is equal to 1.5 (4.5/3 = 1.5)
This means that the ratios are equivalent.
