2.8.3 Solving Other Problems

Question 1

equation

Answer 1

When working with problems with decimals, many people will multiply through by 10, 100, or whatever power of 10 required to “clear” the decimals from the problem. As long as you multiply both sides of the equation, this procedure is valid and protects the balance of the equation. Clearing the decimals helps you think about the numbers involved since most of us prefer to work with whole numbers.
