Answer:
Yes they are.
The ratio of the first trail mix is 3/2
The ratio of the second trail mix is 4.5/3
We can multiply the ratio of the second per 10 and after simplify it to verify what is the ratio:
4.5/3 × 10/10 = 45/30
Simplify 45/30 by 3:
15/10 now simplify it by 5:
3/2
Both ratios are equal to 3/2, so they're equivalent
