120 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to understand how whole numbers and decimals work together. A whole number is a number without fractions or decimals, simply representing a complete quantity. A decimal is a way to represent numbers that are not 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, while those to the right represent the fractional part.

What is 120 as a decimal?

120 as a decimal

 

Answer

 

120 as a decimal is simply 120.0. It is a terminating decimal, showing it does not have any fractional part beyond the decimal point.

 

Explanation

 

To express 120 as a decimal, we recognize that it is a whole number. Since there are no additional fractional parts, it is written as 120.0. The decimal point is used to indicate that there are no fractional parts, but since 120 is an integer, it remains unchanged. Step-by-step breakdown of the process:

 

Step 1: Identify the whole number, which is 120 in this case.

 

Step 2: Since there are no fractional parts, place a decimal point followed by a 0 to indicate it is a decimal representation.

 

Step 3: The result is 120.0, which is equivalent to the whole number 120.
