Answers will vary. Sample response:

When you multiply both sides of an equation by a common denominator or power of ten, every term is being

increased by the number being distributed. For example, when you multiply an equation by 10, you are making

all terms ten times bigger. You can multiply by any number as long as all terms are increased by the same

amount. This preserves the balance in the equation and keeps both sides equal.
