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.
