18 as a Decimal
It is a simple question on decimal representation. Firstly, we have to understand numbers and decimals. A whole number represents a complete quantity. A decimal is a way to represent numbers that include fractions of a whole, 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.
