Pennsylvania has a land area of 44,816 square miles. What is the land area of Pennsylvania rounded to the nearest hundred? How do you know?

Verified Answer :

Answer:

\(44,800\ mi^2\)

Step-by-step explanation:

we know that

To Round a number

a) Decide which is the last digit to keep  

b) Leave it the same if the next digit is less than \(5\) (this is called rounding down)  

c) But increase it by  \(1\) if the next digit is  \(5\) or more (this is called rounding up)

In this problem we have

\(44,816\)

We want to keep the digit \(8\)

The next digit is \(1\) which is less than \(5\), so no change is needed to \(8\)

therefore

the answer is  

\(44,800\ mi^2\)
