It is a simple question on decimal representation. Firstly, we have to understand whole numbers and decimals. A whole number is an integer, which can be positive, negative, or zero. A decimal is a way to represent a number that is not necessarily whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole part, and those to the right represent the fractional part.
