As below.

If ratio of L H S equals ratio of R H S, , then it forms a proportion.

But $12/24$ when reduced, becomes $1/2$

Since $1/2 != 3/4$ , the pair do not form a proportion.

See below:

We know these form a proportion if they are equivalent.

We can reduce $12/24$ to $2/4$ . Now, let's compare our fractions:

$2/4$ and $3/4$

We have the same denominators, but different numerators, so these are obviously not equal, thus they don't form a proportion.

Hope this helps!
