Practice makes perfect
We want to round the given decimal number to the nearest whole number.
0.05
When rounding to any decimal place, we always look at the digit to the right of the one we want. Rounding decimals to the nearest whole number is the same as rounding to zero decimal places. To round to the nearest whole number, we need to look at the first decimal digit.

0. 05
If this digit is less than 5, we round down to the nearest whole number. Rounding down means that we remove all of the digits to the right of the whole numbers place. If the digit is greater than or equal to 5, we round up to the next highest whole number. Then we remove all of the digits to the right.
Next Decimal Digit:& 0,1,2,3,4 → round down
Next Decimal Digit:& 5,6,7,8,9 → round up
In our case, the digit in the tenths place is 0. This means that we need to round down to the nearest whole number.
We found that 0.05 rounded to the nearest whole number is 0.
