How do you know if the pair #12/24 and 3/4# form a proportion?

As below.

Explanation:

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:

Explanation:

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!
