Question

round 16.27 to the nearest one.

Explanation:

Step1: Identify the digit to check

To round 16.27 to the nearest one (whole number), we look at the tenths place digit. The number is 16.27, so the tenths digit is 2.

Step2: Apply rounding rule

The rounding rule for whole numbers is: if the digit in the tenths place is less than 5, we round down (keep the whole number part as it is); if it's 5 or more, we round up. Since 2 < 5, we round down. So 16.27 rounded to the nearest one is 16.

Answer:

16
