No.

Explanation:

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

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

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

However, $\frac{3}{2}$ $3/2$ and $\frac{18}{12}$ $18/12$ are in proportion.
