Answer: 162.2
Explanation:
When rounding to a certain decimal place remember the placements of which number you are rounding
In this case, the 2 behind the decimal is in the tenth place and the 1 is in the hundredth place. So the number we'll be rounding is 2 since it's in the tenth place.
Now when we round a number remember that if the number right of the number you're rounding is 4 or less we keep the number but if it's 5 or more we add 1 to the number we're rounding.
So in this case, because the number right of 2 is 1 we don't change the 2
So our rounded decimal looks like 162.2
