To determine if either of the given equations is a proportion, we need to express each equation as a fraction and then check if the cross products are equal.
-
For the first equation,
:- This can be expressed as
. - Clearly, both sides are not equal, thus it is not a proportion.
- This can be expressed as
-
For the second equation,
:- This can be expressed as
. - Again, both sides are not equal, thus it is also not a proportion.
- This can be expressed as
Now, examining the ratios:
-
The ratio
simplifies to . -
The ratio
simplifies to as well. -
Hence,
is indeed a proportion. -
The ratio
simplifies to . -
The ratio
simplifies to as well. -
Hence,
is also a proportion.
Thus, we conclude that:
is not a proportion, and is not a proportion.- The fractions
and are proportions.
Final Answer: Neither is a proportion.
