If the number was 446,225 and up, then it would be rounded to 446,230, but since it is lower than that it rounds down, not up.

Hi there AngelFace ツ

Rounding Question::

Let me give you an insight of how to round:

● You round up if the number in the selected column is below 5.

● You round down if the number in the selected column is 5 or above.

So; your questions asks us to round the number: 446,221 [Standard Form] to the nearest 10. If we look in the 10's (tens) column, the number is 21. 21 rounded to the nearest 10 is: 20! Therefore; our number is now 446,220 <--- The Answer

Hope this helped :)
