No.

Explanation:

For two fractions to be proportional, they must be equivalent. 3/2 = 1.5 and 18/8 = 2.25, so these fractions are not proportional.

Another way to check is by noting that the numerator of 3/2 is multiplied by 6 to give you 18, but the denominator is only multiplied by 4.

And, since 6 obviously doesn't equal 4, this is another check.

However, 3/2 and 18/12 are in proportion.
