Filomena applies the commutative property to the product. (7/15)⋅(−11)⋅(30) Which expression illustrates the commutative propert
dedylja [7]

  • The commutative property is a number property where the answer obtained is the same no matter the position of the numbers you are multiplying together.

  • Commutative property of multiplication is expressed as:

        a x b = b x a

        a x b x c = a x c x b = b x c x a

  • Note: " . " in the question also means "x" (multiplication)

  • Applying commutative property to the question:

(7/15)⋅(−11)⋅(30)

(7/15) ⋅ (−11) ⋅ (30) = (7/15) . (30) . (11)

The values interchanged are: 11 and 30. The result of the multiplication remains unchanged.

Option A  is the correct answer.
