Step-by-step explanation:

In rounding up numbers, numbers 1 to 4 would be rounded up to 0, while 5 to 9 would be rounded up to 1.

Depending on the question, we can be asked to round up to the nearest ten, hundred, thousand, one decimal place, two decimal place, whole numbers and etc. In whatever case, we look at the number directly before the number concerned from the right hand side, and then approximate based on the law of rounding up.

In the question above, we have 81.46 and told to round up to the nearest whole number. 81, is the whole number here, so what number precedes 81 from the right, and to number is 4. 4 would be rounded up to 0. Hence, we have 81.0
