12.2 is already rounded to the nearest tenth. This is because it has a single digit after the decimal point, indicating that it is already in the tenths place.
The question is asking about rounding a number to the nearest tenth. When rounding to the nearest tenth, we look at the number in the hundredth place. Since 12.2 only has digits in the tens and ones places, there are no additional digits in the hundredths place that might change the tenth place on rounding.
Therefore, 12.2 is already rounded to the nearest tenth because it has a single digit after the decimal point, which represents tenths. The number itself does not change when we're rounding to the tenth place.
