Step-by-step explanation:
The expression that Renee is simplifying is:

It is provided that, Renee recognizes that 7 and
are reciprocals, so she would like to find their product before she multiplies by
.
The associative property of multiplication states that:

The commutative property of multiplication states that:

The distributive property of multiplication states that:

The identity property of multiplication states that:

So, Renee should use the commutative property of multiplication to find the product of 7 and
,

Thus, the correct option is commutative property.
ANSWER
The correct answer is D.
EXPLANATION
If we express the monomial,

as product of primes, we obtain:

If we express the monomial

as product of primes we obtain:

The least common multiple of these two binomials is the product of the highest powers of the common factors.
The LCM is


Therefore the correct answer is D.
