The 4 represents the number that we'll be looking at since 4 is the next position to the right of 8, 8 is in the Tenths place. 4 is in the Hundredths place, and 4 will be the only number that <u>could</u> round up the 8.
<h3>How?</h3><h3 />
In order to round, we need to remember how to round numbers:
If the digit is less than 5, the number to the left stays the same.
If the digit is greater than, or equal to 5, the number to the left rounds up, or increases by 1.
<h3>Solve:</h3><h3 />
First, 4<5, meaning that 4 is <u>less</u> than 5.
<u>#1 above is stating that the number to the left of 4 stays the same.</u>
