What is 105.27 rounded off to the nearest whole number?

Short answer: 105

Explanation: A whole number is one without a decimal. When you're rounding, take a look at the decimal. if the decimal is less than .50, then you round down to the current whole number, in this case 105. If the decimal is .50 or above, you round up to the next number, in this case, 106. Since the decimal is .27 we round down to 105.
