The missing property is B) multiplication. The property is called the Multiplication Property of Equality, which states that if a = b, then ac = bc.
The property you are referring to is the multiplication property. It states that if two quantities are equal (a = b), then multiplying both sides of the equation by the same number (c) will still result in equality (ac = bc). This property is a fundamental concept in algebra and is often used in solving equations.
