Answer :

Final answer:

Kelly is using the Associative Property of Multiplication to simplify her calculations. This mathematical property allows the changing of grouping of numbers without altering the final product.

Explanation:

In the given scenario, the property of multiplication being used by Kelly is known as the Associative Property of Multiplication. This property states that the way in which numbers are grouped does not change the product. In mathematical terms, it is (ab)c = a(bc). In Kelly's case, it is (5 x 173) x 20 = 5 x (173 x 20), which is the application of the associative property. The result remains the same as 17300.
