Final answer:
The correct method is to multiply by 1/3.
Step-by-step explanation:
The correct method to solve the equation using the multiplication property of equivalence and the reciprocal of 1/3 is b) Multiplying by 1/3.
When we multiply both sides of an equation by a fraction or its reciprocal, it is important to remember that the operation applies to every term on either side of the equation. By multiplying both sides by 1/3, we are using the multiplication property of equivalence to maintain equality.
For example, if we have the equation 2x = 6, multiplying both sides by 1/3 gives us (1/3)(2x) = (1/3)(6), which simplifies to (2/3)x = 2.
