It is a simple question on decimal conversion. Firstly, we have to understand whole numbers and decimals. A whole number is a complete entity without fractions or decimals. A decimal is a way to represent numbers that include a fraction of a whole number, using a (.) or a decimal point to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
