Do the ratios 13/14 and 1/2 from a proportion

No, I believe not

Step-by-step 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
