Question 23377
<pre><font face = "courier new" size = 2>how to round off 8,008,278 to the nearest ten thousand.
<b>
First let's name all the digits, starting at the far right and moving
to the left.

8 (on the far right) is the one's digit
7 is the ten's digit
2 is the hundred's digit
8 (the 8 in the middle)is the thousand's digit
0 (the 0 farthest to the right) is the ten-thousand's digit
0 (the 0 farthest to the left) is the hundred-thousand's digit
8 (the 8 on the far left) is the million's digit

Since you are to round off to the nearest ten thousand, I will color
the ten-thousand's digit, the right-most 0, <font color = "red">red</font>,
and the digits to the right of it <font color = "blue">blue</font>:

                  8,0<font color = "red">0</font><font color = "blue">8<font color = "black">,</font><font color = "blue">278</font><font color = "black">
 
We look at the digit just right of that <font color = "red">0</font>.  It is an <font color = "blue">8</font>.  Since <font color = "blue">8</font> is 5 or more
we add one to the <font color = "red">0</font> in the ten-thousand's place, getting <font color = "red">1</font>, so we replace that
<font color = "red">0</font> in the ten-thousand's place by <font color = "red">1</font>.  Then we replace ALL digits to the
right of that ten-thousand's digit with 0's

Final result:
                  8,0<font color = "red">1</font><font color = "blue">0<font color = "black">,</font><font color = "blue">000</font><font color = "black">
