A) Multiply both sides of the equation by a common factor.
B) Divide both sides of the equation by a common factor.
C) Add a constant to one side of the equation.
D) Subtract a constant from one side of the equation.

Answer 1

To solve for proportion in an equation, you can multiply or divide both sides of the equation by a common factor.

Step-by-step explanation:

Multiplication or division by the same number on both sides of an equation does not change equality. Remember that multiplication or division should apply to every term on either side of the equality. Enclose the side with more than one term in small brackets and then do the multiplication of division operation so that it applies to each term in the bracket. Multiplying both sides of the equation with leads to:
