How do you round off the whole number?
Whatever place you are rounding off to, look to the digit to the right of it. If it is 4 or less, the digit you are rounding stays the same and everything to the right of it becomes a zero. If the digit to the right of it is 5 or greater, the number you are rounding becomes one greater and everything to the right of it becomes a zero.
For example, if I am rounding to the nearest 100 in each of these.
12348 becomes 12300
74862 becomes 74900
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.
