See explanation

#### Explanation:

Method 1

Let $k$ be some constant. Then we have

$\frac{1}{2} \times \frac{k}{k} = \frac{3}{6}$ if $k$ exists then they are a proportion

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Method 2

If the answer is 1 then they form a proportion.

$\frac{1}{2} \div \frac{3}{6} = 1$
