Answer: No


Step-by-step explanation:

You should write down all the numbers as simplified fractions to see if they are proportional

1/4 stays as 1/4

2/6 is simplified as 1/3

3/12 is simplified as 1/4

and 4 out of 18 is simplified as 2/9

Since the simplified fractions are not the same, it's not proportional :)
