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. A decimal representation does not require a decimal point.

What is 4.875 rounded off to one decimal?

Your 4.875 rounded off is 4.9 to one decimal. When rounding off to one decimal, we look at the second decimal. When the second decimal is 5 or more, we round the first decimal up by one. In this case, the second decimal is 7, and that means we round the first decimal, the 8, up by one, and that makes it 9. That's where the 4.9 came from.
