Name the place value, and we'll zero in on it.
You cannot round a number with a place value larger than the place value you seek to round it to. i.e. You cannot round thousands to hundreds, hundreds to tens, tens to ones, etc.
It is 63.452

To round to 1 decimal place you look at the numbers after the first decimal place onwards. If the value is more than 5 (or 50 or 500 etc) then round up, if the value is less than 5 then round down. If the value is exactly 5, then some statistically naive people suggest round upwards. The correct procedure, so as not to introduce an upward bias, is to round up or down so that the last digit left is even. Here the number after the first decimal place is 74 - well above 50. So you round up. 2.8xx, rounded up is 2.9

To round off 4.73 to one decimal place, you would look at the digit in the second decimal place, which is 3. Since 3 is less than 5, you would keep the digit in the first decimal place the same. Therefore, rounding 4.73 to one decimal place would result in 4.7.

To round 0.849 to one decimal place, you look at the digit in the second decimal place, which is 4 in this case. Since 4 is less than 5, you simply truncate all digits after the first decimal place, leaving you with 0.8 as the rounded value.

Since 54 is an integer, there is no need to round it to any number of decimal places.
-- If the place to the right of the place named contains a digit larger than 4, then add ' 1 ' to the digit in the place named. If not, then don't. -- Discard all digits to the right of the place named.
Currently it is not rounded to anything. You can round 14.5 to the nearest tens place. When you round it to the tens place you will get: 15. This is because the ".5" value in the decimal.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. So, a decimal number will always round to a decimal number.
