Rounding Numbers Test #3

In this section, we learn about rounding numbers. Specifically, we will focus on how to round with whole numbers. Often, an exact value is not needed. Let’s suppose we are looking at cars. We might find that a model X car costs $29,755.78, whereas a model G car costs$40,226.38. To make matters simple and easy to remember, we may just say the model X car costs about $30,000 and the model G car costs about$40,000. These values of $30,000 and$40,000 represent approximations. An approximation is an estimate or value that is close, but not exactly the same as the original. Rounding a whole number is a way to give an approximation. To round a whole number, first we must identify how precise we want our approximation to be. This stems from giving a round off place. Once this is known, we begin our procedure:
