Round 12.231 to the nearest ten.

Darn my answer with the explanation was deleted. I'll answer again.

Note:

-The tens place is the second digit to the left of the decimal place.

-Round up when the digit is 5, 6, 7, 8, or 9.

-Stay when the digit is 0, 1, 2, 3 or 4.

12.231 rounded to the tenths is 10
