Answer:
They do not form a proportion.
Step-by-step explanation:
To determine if they are a proportion, you can cross multiply and get the same answer on both sides. So, we multiply the numerator from the first by the denominator in the second.
12 * 3 = 36
Now we use the denominator from the first side and the numerator on the second side.
15 * 2 = 30
Since they are not equal, it is not a real proportion.
