18 as a Decimal

Professor Greenline Explaining Math Concepts

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.

Answer

18 as a decimal is simply written as 18.0. This is because 18 is a whole number and does not have any fractional part.

 

Explanation

To express 18 as a decimal, we recognize that it is already a whole number. If we want to emphasize that it has no fractional part, we can write it as 18.0.

 

 

Step 1: Identify the whole number, which in this case is 18.

 

Step 2: Since there is no fractional part to consider, the decimal representation remains 18.0. There are no further steps needed, as 18 is a terminating decimal.
