To determine if both fractions are equivalent, it must support the expression:

where a and b are the fractions.
We need to simplify both fractions to check if they are equivalent.
First Fraction:

We can divide both the numerator and denominator by 3:

Second Fraction:

We can divide both the numerator and denominator by 4:

Putting these into the expression to check equivalency, we can see that:

Therefore, BOTH FRACTIONS ARE NOT EQUIVALENT.
