Answer:
No, I believe not
Explanation:
If these fractions were to form a proportion among one another, it would be that 13 / 14 should simplify to 1 / 2, but;
13 / 14 ( simplified ) ⇒ 13 / 14
Now there is another way to check if these fractions do form a proportion, by forming the proportion itself, applying cross multiplication to identify if either side is equivalent to one another;
13 / 14 = 1 / 2,
13 * 2 = 14 * 1,
26 ≠ 14,
Answer; Thus these ratios really don't form a proportion among one another
