what is 15.999 rounded to the nearest tenth

16.0

Isn't $15.99 about $16.00?

To round a number to the nearest tenth, you need to look at the digit in the hundredth's place (the first decimal place) and determine whether to round up or down.

In this case, the number is 15.999 and the digit in the hundredth's place is 9. Since 9 is equal to or greater than 5, we round up.

To round up, you increase the digit in the next decimal place (the tenths place) by 1. In this case, the digit in the tenths place is 9, so we increase it by 1, resulting in 10.

Therefore, rounding 15.999 to the nearest tenth gives us 16.0.
